Abstract:
The use of packaging films containing natural preservative compounds attracts great attention for the quality improvement of seafood. Microalga spirulina (Spirulina platensis) represents a potential source of high added-value and preservative biocompounds. The goal of this study was to enhance the quality of refrigerated Atlantic mackerel (Scomber scombrus) by including a protein concentrate (PC) of spirulina in a gelatine-based film. Quality changes in fish muscle were monitored by microbial and chemical analyses throughout an 11-day refrigerated storage (4 °C). As a result of the presence of spirulina PC in the film, an antimicrobial effect (p < 0.05) was concluded as determined by comparative evolution of aerobes and psychrotrophs, while no effect (p > 0.05) was concluded for Enterobacteriaceae, proteolytics and lipolytics counts. Furthermore, a lower (p < 0.05) formation of trimethylamine and free fatty acids was detected. Lipid oxidation, measured by fluorescent compounds formation, also exhibited lower average values in fish corresponding to the batch containing spirulina concentrate. The preservative effects observed can be explained on the basis of the presence of antimicrobial and antioxidant compounds in the microalga concentrate. It is proposed that the current packaging system may constitute a novel and promising strategy to enhance the quality of commercial refrigerated fatty fish.

Abstract:
The aim of the study was to investigate the complete substitution of imported soybean meal in beef cattle diets and the consequences on performance, meat, and adipose tissue quality. Thirty growing crossbred Limousin bulls, with an initial bodyweight of 164 ± 13 kg and 4.3 ± 0.3 months of age, were fed a grass/maize-silage based diet with little additional concentrate (0.5:0.3:0.2). Concentrates contained either soybean meal (positive control), faba beans, pumpkin seed cake, or spirulina (Arthrospira platensis), resulting in about 226 g crude protein (CP)/kg concentrate dry matter (DM) and 158 g CP/kg total diet DM. A grain-based concentrate providing just 135 g CP/kg concentrate DM and 139 g CP/total diet DM served as a negative control. Bulls of all groups had comparable average daily gains (1.43 ± 0.1 kg) and feed intakes (6.92 ± 0.37 kg). Carcass and meat quality did not differ among groups. The fatty acid profile of meat lipids was hardly affected. These results indicate that soybean meal can be replaced by any of the tested protein sources without impairing performance or meat quality. Importantly, bulls fed the negative control achieved a fattening and slaughter performance comparable to that of the protein-supplemented groups without affecting meat and adipose tissue quality. Thus, the present findings suggest that feeding crossbred bulls a grass/maize-silage based diet does not require additional protein supplementation.

Abstract:
The intake and in vivo digestibility of Trypsacumlaxum in guinea pigs according to the graded level of spirulina was evaluated in Cameroon. 20 animals aged of 6 months with an average weight of 450 ± 50 g were randomly divided into 4 equivalent groups. Each group received T. laxum and 40g of compound feed containing 0% (TS0), 2% (TS2), 4% (TS4), and 6% (TS6) of spirulina. Feed intake was the different between the left over and the quantity served. The sample of T. laxum and those of each diet as well as feces were collected and analyzed for the apparent digestibility of each nutrient. Animals were weighed at the beginning and at the end of each period of the test to determine the body weight gain. This study showed that the average daily intake of dry matter (DM) for TS0, TS2, TS4 and TS6 was 74.39 ± 2.98, 78.66 ± 3.14, 83.89 ± 4.28 and 77.76 ± 4.40 g/head/day. The highest apparent digestibility coefficients of different nutrients were obtained with animals fed TS6 group while the lowest were observed in TS0.The apparent digestibility coefficient of dry matter (DM), organic matter (OM) and crude protein (CP) of the supplemented group were statistically higher than those of the control diet. Animals’ weight performances were statistically comparable between treatments. Thus, the combination of T. laxum with concentrated feed containing spirulina can be recommended for guinea-pigs, but the level of incorporation may not exceed 4% of its daily ration.

Abstract:
Poultry industry are facing many challenges and osbtacles especially on the supply of feed ingredients, medicines, feed supplements and additives. The high price of protein source-feed ingredients has encouraged nutritionists to explore and utilize alternative protein source-feed ingredients for poultry. This review provides an overview of their nutritional and bioactive contents and the use of microalgae,<em> Chlorella vulga</em>ris and <em>Spirulina platensis</em> in poultry feed based on recent literature studies and their potential development and utilization in Indonesia. The microalgae <em>Chlorella vulgaris</em> dan <em>Spirulina platensis</em> have very high protein content that are potential as a protein source in poultry rations. In addition, <em>Chlorella vulgaris</em> and <em>Spirulina platensis</em> also contain several bioactive compounds that can be used as alternatives to antibiotics growth promoter and synthetic antioxidants for poultry. Indonesia has a great potential for the production of <em>Chlorella vulgaris</em> and <em>Spirulina platensis</em>, however massive cultivation and economies of scale have not yet been carried out. Such conditions make <em>Chlorella vulgaris</em> and <em>Spirulina platensis</em> less profitable as protein sources, but more likely as growth-promoting additives or antioxidants for poultry in Indonesia.

Spirulina platensis is a cyanobacterium that can be consumed by humans, for its high contents of proteins and nutraceutical compounds. This study aimed to develop cookies mixed with S. platensis for nutritional enrichment purposes. The study conducted quality control analyses and elaborated formulations of cookies with different contents of S. platensis (0, 5, 10 and 15%), which were subjected to physical, chemical, microbiological and sensory analyses. In the cookies, the increase of S. platensis percentage led to increment in protein percentage, besides increments in minerals, compared with the cookie produced with only refined wheat flour. Cookies with 15% of S. platensis (F5) stood out regarding the percentages of protein and minerals, and were similar to the whole cookies with respect to the minerals; lipids and highest energetic value were observed in the standard cookies. Cookies mixed with 5% of S. platensis and standard cookies were preferred with the same score, indicating a possible acceptance in the market.

The aim of this study was to evaluate the physicochemical properties of Spirulina colored soluble protein fractions extracted from spray-dried Spirulina powder. Three fractions, including the blue soluble Spirulina protein, the green soluble Spirulina protein, and the total soluble Spirulina protein fractions were obtained. Investigations on their behavior at air/water interface were carried out using dynamic methods of drop volume and bubble pressure surface tension measurements. Evaluation of their monolayer films’ mechanical behavior was done via compression isotherms using Langmuir film balance. The protein contents of the fractions were 82.76, 82.29, and 74.53% for the blue, the green, and the total fractions, respectively. Surface tension decay increased with increasing concentration for all the fractions. No significant difference in surface tension decay was observed between the samples at 0.3% (w/w). Surface tension decay was less important at pH 3 for all the fractions. The total fraction and the blue fraction appeared to form more elastic films than the green fraction. The blue soluble fraction also presented the highest collapse pressure and initial expansion area.

Abstract:
Wheat flour is the most important raw material in the production of pasta. The production process consists of mixing water and flour, kneading, extrusion and drying. Oats and the microalga Spirulina platensis play a physiological role in the growth, development and maintenance of the human organism due to their high nutritional value. The aim of this study was to assess the technological and nutritional properties of dry pasta prepared with the addition of oatmeal and Spirulina platensis. The wheat flour was characterized and the effect of partial replacement by oatmeal and Spirulina platensis (Arthrospira platensis) was evaluated using response surface methodology (RSM). The mixtures were analysed for moisture, protein, ash, colour, particle size, falling number and alveography. The formulated pastas were dried and evaluated for moisture, colour, cooking test, acidity, proximate composition and amino acids. Generally, the addition of Spirulina platensis influenced the soluble solids content and colour of the pasta, while the oatmeal mainly affected the acid content. The oatmeal increased the values of crude protein and total dietary fibre (13.06%) when compared with the commercial pasta (2.40%) and may be considered as a source of fibre.

Abstract:
Spirulina platensis is a filamentous cyanobacterium that has been commerically used for fish feed and human food supplement. Low-cost production of Spirulina is needed when considering large-scale culture especially for industrial purposes. The aim of this study was to explain the effect of calcium nitrate (Ca(NO3)2) on growth, biomass, pigment, and protein production of S. platensis and to determine the best calcium nitrate concentration for Spirulina production.The microalgae was cultured at four calcium nitrate concentrations (1, 1.5, 2.0 and 2.5 g/L) with salinity of 15 ppt, constant light intensity of 4,000 lux and photoperiod of 24:0 light:dark cycles for 4 days. The results showed that different calcium nitrate concentrations remarkably affected the growth, biomass production, pigment and protein content of S. platensis (p<0.05). The highest specific growth rate of 0.721 day-1 and biomass concentration of 1.512 g/Lwere achieved at calcium nitrate concentration of 2.5 g/L. Moreover, the algae had the highest chlorophyll-a, carotenoid and protein content at 2.5 g L-1. Increasing calcium nitrate concentration from 1 to 2.5 g/L led to an increase in biomass, pigment and protein production of S. platensis. However, there was no significant difference between 2 and 2.5 g L-1 calcium nitrate concentrations. We suggest that 2-2.5 g/L Ca(NO3)2 concentration can be used profitably for S. platensis production.

Abstract:
Microalgae Spirulina platensis contains high protein which can be used as functional food, but it has several undesirable volatile compounds. Ocimum basilicum contains various essential oils from the monoterpene class that can be used to reduce volatile compounds causing an off-odour in Spirulina platensis. This study was conducted to evaluate the intervention of O. basilicum on nature and microencapsulated S. platensis powder after O. basilicum treatment against the volatile compounds. The research consisted of two intervention models. S. platensis powder soaked with basil extract (1:4, w/v) and then dried by freeze-drying method without microencapsulation (DSB). The S. platensis powder was soaked in basil extract (1:4, w/v) then dried by freeze-drying method and microencapsulated (MSB) after. Spirulina platensis powder was used as a control (SP). A solid-phase microextraction was used with the combination of GC-MS to identify volatile compounds. The results showed that the main volatile compounds in Spirulina are medium-chain alkanes. Other compounds that contributed to this off-odour are geosmin (0.02%), 2-Methylisoborneol (0.28%), β-ionone (4.94%). The intervention of O. basilicum in S. platensis resulted in a decrease in these volatile compounds. Geosmin was not detected by intervention with O. basilicum either by microencapsulation (MSB) or without microencapsulation (DSB). Therefore, the intervention of O. basilicum can reduce off-odour in S. platensis and can be applied as a functional food

Abstract:
Spirulina platensis, microalgae, is emerging as a sustainable source for highly nutritional food ingredient production to cover the food demands of the global population. This study aimed to characterize food prototypes supplemented with microalgae protein isolate to develop health-promoting food products. The nutritional composition (proximate composition, fatty acids, and mineral content) of the spirulina biomass, the structural characterization of spirulina platensis protein (SPP) isolates, and the physicochemical properties of SPP- developed food products were evaluated. High protein (47%), ϒ-Linolenic acid (24.45 g/100 g of fat), iron (16.27 mg/100 g), calcium (207 mg/100 g), and potassium (1675 mg/100 g) content in the spirulina biomass was found. SPP (76% of purity) with sodium alginate produced stable emulsions (>90%) during storage (14 days). Amaranth + SPP pasta resulted in good appearance, texture, color, and high nutritional value in protein (above 30%) and minerals, mainly iron (9–10 mg/100 g) and magnesium (300 mg/100 g), meeting the daily intake recommendations. In addition, the amino acid profile of the pasta was in line with the amino acid pattern requirements for adults. SPP can be considered as potential additive for emulsions stability and provided nutritional and physicochemical desired in the elaborated pasta.

The major physical, chemical, microbiological, and sensory properties of croissants enriched with Spirulina at concentrations ranging between 0.5 and 1.5% were evaluated. The results showed that the use of A. platensis biomass for the production of croissants improved the textural and organoleptic properties of the final products. Spirulina fortification also increased the protein and moisture levels and water-holding capacity, whereas it decreased the crumb firmness and lightness of croissants. Optimum sensory results were obtained when Spirulina was applied at a rate of 1%. Besides these benefits, the A. platensis biomass enhanced the levels of biologically active substances (i.e. essential amino acids, chlorophyll, phycocyanin, carotenoids, minerals, vitamins, and essential fatty acids) in croissant samples. To our knowledge, this is the first scientific study on Spirulina-fortified croissants.

Abstract:
Lipid metabolism disorder (LMD) is a public health issue. Spirulina platensis is a widely used natural weight-reducing agent and Spirulina platensis is a kind of protein source. In the present study, we aimed to evaluate the effect of Spirulina platensis protease hydrolyzate (SPPH) on the lipid metabolism and gut microbiota in high-fat diet (HFD)-fed rats. Our study showed that SPPH decreased the levels of triglyceride (TG), total cholesterol (TC), low-density-lipoprotein cholesterol (LDL-c), alanine transaminase (ALT), and aspartate transaminase (AST), but increased the level of high-density-lipoprotein cholesterol (HDL-c) in serum and liver. Moreover, SPPH had a hypolipidemic effect as indicated by the down-regulation of sterol regulatory element-binding transcription factor-1c (SREBP-1c), acetyl CoA carboxylase (ACC), SREBP-1c, and peroxisome proliferator-activated receptor-γ (PPARγ) and the up-regulation of adenosine 5’-monophosphate (AMP)-activated protein kinase (AMPK) and peroxisome proliferator-activated receptorα (PPARα) at the mRNA level in liver. SPPH treatment enriched the abundance of beneficial bacteria. In conclusion, our study showed that SPPH might be produce glucose metabolic benefits in rats with diet-induced LMD. The mechanisms underlying the beneficial effects of SPPH on the metabolism remain to be further investigated. Collectively, the above-mentioned findings illustrate that Spirulina platensis peptides have the potential to ameliorate lipid metabolic disorders, and our data provides evidence that SPPH might be used as an adjuvant therapy and functional food in obese and diabetic individuals.

Abstract:
Pasta has an important role in human nutrition for its high content of complex carbohydrates and its widespread use. It can be an efficient delivery system or carrier of non-traditional raw material, including additional health-promoting ingredients. The partial replacement of semolina with high-protein raw materials leads to the improvement of the biological value of pasta proteins. In order to obtain pasta with high nutritional protein value and with excellent cooking properties, various recipes have been formulated with different percentages of semolina and unconventional high-protein raw materials (peas and soy isolate proteins, egg white, whey proteins and Spirulina platensis). High-protein pasta was produced using a pasta making pilot plant and the nutritional quality (protein content and quality) and sensorial properties were assessed. All experimental pastas showed optimal performances. Pasta prepared with pea protein isolate, whey proteins and Spirulina platensis showed improved chemical score and digestible indispensable amino acid scores, an eye-catching color, and an excellent cooking quality.

Abstract:
The addition of Spirulina platensis in chocolate bar was reported to be able to increase the carotenoid content. Unfortunately, the fortified dry biomass generated fishy odor. In recent years, we succeeded to extract carotenoid from S. platensis, which was then encapsulated using a mixture of gum arabic and WPC by nanoemulsion technique. It helped reduce the fishy odor and concentrate carotenoid content in the nanocapsules. This study aimed to determine the effect of S. platensis’s carotenoid nanocapsules on the flavor profiles of dark and milk chocolate. The S. platensis’s carotenoid nanocapsules were added at a dose of 0.37% (w/w). Flavor profiles were detected using Gas Chromatography-Mass Spectrometry. A total of 79 aroma active were detected. The dark chocolate had a specific aroma of strong acidic chocolate, enriched with creamy and sweet. Meanwhile, the milk chocolate was dominated by creamy, cheesy, and sweet. The fortified chocolate had lower concentration of acids and aldehydes but had higher pyrazines and alcohols. Volatile compound that responsible for the fishy odor in Spirulina platensis was not detected in fortified chocolate. In conclusion, the fortification increased the intensity of sweet and chocolate flavor, decreased the bitter and sour flavor, and did not generate any unpleasant odor.

Abstract In order to assess ability of Spirulina platensis to recover silver and gold ions from the environment the bioaccumulation of silver and gold ions and their effect on growth, proteins and carbohydrates content of Spirulina platensis biomass was studied. Silver nitrate (AgNO3) in concentration range 0.01-1 mg/dm3 and tetrachloroaurate Na[AuCl4] in concentration range 18.5-370 mg/dm3 were added as component of the Spirulina platensis cultivation medium. In case of silver two cultivation media were studied: standard and Cl-free. The process of silver and gold uptake was traced using neutron activation analysis. Presence of silver ions in standard cultivation medium reduced biomass productivity by 66 %, while in Cl-free biomass productivity was reduced by 11.8 % only. The reduction of proteins content by 30 % in Cl-free medium and by 19 % in standard medium was also observed. The experiments showed that in case of gold ions loading, the biomass productivity and protein content were reduced only at high Na[AuCl4] concentration in the medium. The behaviour of carbohydrates content change was similar under silver and gold loadings: decrease at low metal concentration followed by increase at high metal concentrations. Scanning electron microscopy allowed observation of spherical metal nanoparticles, which were formed extracellularly during silver and gold bioaccumulation. Spirulina platensis can be used for recovery of precious metals as well as metal nanoparticles production.

Abstract:
Spirulina platensis is a blue-green microalga which is classified into Cyanobacteria. S. platensis is often used as functional food ingredient because their phycocyanin pigment has antioxidant properties. However, the pigment is of low stability and is sensitive to temperature, pH, oxygen, and humidity. The purpose of this study was to determine the effect of microencapsulation and pH treatment on the stability of phycocyanin S. platensis. The experimental design used in the study was Completely Randomized Factorial Design with 2 factors namely microencapsulation process and different pH values (pH 4 and pH 8). The results showed that the microencapsulation process and pH treatment had different effects (P <0.05) on the stability of phycocyanin. S. platensis with microencapsulation at pH 8 produced smaller phycocyanin degradation (5.32±1.37%), antioxidant degradation (38.12±0.31%), and total color different (TCD) (22.1±0.07) compared to other treatments. While the relative concentration (CR) value of the microencapsulated phycocyanin in S. platensis was 94.68±1.37%, higher than that of other treatments. Microencapsulation at pH 8 stabilized phycocyanin by preventing precipitation of the protein.

Abstract:
Spirulina platensis, the most popular microalgae species known for its high protein content and bioactive compounds such as phycocyanin and allophycocyanin, has been studied for cheese fortification. Incorporation of spirulina in dairy products poses major sensorial challenges due to its characteristic odor and its insolubility in food formulation, thus limiting consumer acceptance. The main objective was the production of a novel spread cheese fortified with spirulina, so powdered spirulina was added at different concentrations (0.25, 0.5, and 1%), and the effect on physicochemical, microbiological, and sensory characteristics was assessed. Cheese samples were examined for pH, fat (Gerber-Van Gulik method), salt (Volhard method), protein (Kjeldahl), and moisture content by drying to constant weight at 102 ± 1 °C. Cheeses were also assessed organoleptically by five experienced panelists. Generally, the addition of spirulina slightly increased the protein content and affected the color of the cheeses. The cheeses achieved a good microbiological profile and were all characterized as acceptable for consumption by the panelists. However, the cheeses with 0.25 and 0.5% spirulina were mostly preferred by the evaluation panel due to the less intense characteristic odor and taste of spirulina. We conclude that it is possible to produce an acceptable spread cheese with the addition of spirulina without significant changes in the cheese production line.

Abstract:
An attempt was made to assess the suitability of the inland saline water of Rohtak (Haryana) for mass cultivation of Spirulina platensis, a salt loving cyanobacterium. Cultivation of S. platensis was performed in indoor and outdoor culture units. The investigation revealed that the yield of biomass in de-calcified inland saline water was comparable to the yield obtained in synthetic chemical-based prescribed growth medium. Further, the quality of biomass in terms of protein, chlorophyll a, carotenoids and phycocyanin contents was also comparable to the prescribed medium. The downstream processing of the biomass through a three-step process resulted in an appreciable quantity of a highly valuable pigment, phycocyanin (purity ratio: A620/A280 = 3.13–3.39). The overall observations of the study suggest that inland saline water can be used for cost-effective production of Spirulina biomass and value-added chemicals. The removal of calcium and salts from inland saline water by S. platensis cultivation also offers an added advantage for the reuse of the spent medium for agricultural and aquacultural purposes.

Abstract:
Abstract: The objective of this work was to develop dehydrated soup formulations using flour from peach palm by-product (PPB), Spirulina platensis or spinach, as well as to evaluate their composition by physical, chemical, instrumental, and sensory methods. Four formulations were developed: standard, PPB flour, PPB flour and S. platensis, and PPB flour and spinach. The samples were analyzed for proximate composition, chlorophyll content, total phenolic compounds, antioxidant activity, color, viscosity, water absorption, and microbiological parameters. The sensory characterization was performed by the check-all-that-apply method. The soups containing spinach or S. platensis presented the highest protein contents of 3.3 and 4.6 g 100 g-1, respectively. The soups formulated with the microalgae S. platensis showed higher contents of fibers, lipids, and antioxidants. Changes were observed in the color and viscosity of the soups. The standard dehydrated soup was characterized as shiny, creamy, with seasoning flavor and fragments, and a pale-yellow color; the formulation with spinach, as grainy, with an herb odor and flavor, seasoning fragments, and a dark-green color; and with S. platensis, with herb flavor, seasoning fragments, and a dark-green color. The developed formulations are within the microbiological standards for food established by the Brazilian legislation. The sensory analysis revealed a new market niche, and the soups containing PPB and S. platensis showed good acceptability. Peach palm flour, Spirulina platensis, and spinach are alternatives for the nutritional enrichment of dehydrated soups with high protein, ash, fiber, and antioxidant contents.

Abstract:
Abstract We evaluated the microalga Arthrospira platensis (commonly called spirulina), as a pollen substitute for honey bees. Nutritional analyses indicated that spirulina is rich in essential amino acids and a wide variety of functional lipids (i.e., phospholipids, polyunsaturated fatty acids, and sterols) common in pollen. Feeding bioassays were used to compare dry and fresh laboratory-grown spirulina with bee-collected pollen and a commercial pollen substitute using sucrose syrup as a control. Diets were fed ad libitum as a paste to newly emerged bees in cages (10–13 cage replicates) and bees were sampled at days 5 and 10 for physiological and molecular measurements. Spirulina diets produced biomarker profiles (thorax weight, head protein content, and beneficial gut bacteria abundance) that were indicative of elevated nutritional states, meeting or exceeding the other diets in some metrics despite reduced consumption. Furthermore, spirulina diets led to significantly increased fat body lipid content and mRNA levels of the central storage lipoprotein vitellogenin. We conclude that spirulina has significant potential as a pollen substitute or prebiotic diet additive to improve honey bee health.

Abstract:
Arthrospira platensis (spirulina), a filamentous fresh-water planktonic cyanobacterium, possesses diverse biological activities and a unique nutritional profile, due to its high content of valuable nutrients. This study aimed to further improve the bioactive profile of spirulina, by fermenting it with the lactic acid bacterium Lactobacillus plantarum. In vitro comparison of the total phenolic content (TPC), C-phycocyanin, free methionine, DPPH radical scavenging capacity, ferric reducing antioxidant power (FRAP), oxygen radical absorbance capacity (ORAC) and protein fragmentation via SDS-PAGE in untreated versus 12 to 72 h fermented spirulina is reported here. After 36 h fermentation, TPC was enhanced by 112%, FRAP by 85% and ORAC by 36%. After 24 h, the DPPH radical scavenging capacity increased 60%, while the free methionine content increased by 94%, after 72 h. Past 36 h of fermentation, the total antioxidant capacity (TAC) diminished, possibly due to deterioration of the heat-sensitive antioxidants. However, protein fragmentation and free methionine content increased, linearly, with the fermentation time. Cyanobacterial peptides and other bioactive compounds trapped within the spirulina cell wall are released during fermentation and have a significant potential as a functional ingredient in nutraceuticals and pharmaceuticals, in addition to their nutritive value.

Abstract:
In the present study, the blue-green alga Spirulina platensis (NRC) was used for mass production under outdoor cultivation in three open ponds with a final capacity of 75 m3 net cultivation volume. Subculturing was performed within sequences and gradual volumes till 1,200 L open plate photobioreactor. The first and second ponds (30 cm depth) were used for the actual continuous production, while the third pond (80 cm depth) was used as a continuous inoculum supplier. In spite of low turbulence of the third pond due to high depth, all ponds had the same mechanical specification concerning paddle wheel structure and turbulence rate (16 rpm). A final nutrient concentration was employed based on Zarrouk medium by commercial grade compounds with some modifications. The nutrition was performed for the third pond by extra supplementation of extra doses of macro and micro-nutrients during the production period and dilution took place when culture was transferred to production ponds (first and second). Each production pond was harvested every 48 hours and the remainder water was return again into the third pond. The harvested pond yielded about 40 kg per day of fresh algal weight containing about 85% moisture on a dry weight basis. The results proved that using urea as nitrogen and carbon source with corn steam liquor instead of sodium nitrate and low bicarbonate, reduces production cost and supports growth medium by an adequate amount of carbon dioxide on the expense of the luxury use of sodium bicarbonate (16.8 g.l-1). Chemical analysis of the produced biomass showed 58-62% crude protein, 6-8% of ether extract and 8-11% of total carbohydrates. S. platensis contained total essential amino acids (131.3 mg/g), with a predominance of arginine followed by glutamic acid, leucine and phenylalanine.

Abstract:
Spirulina is an algae that grow in fresh and sea water and itself known to the human community with its unique Neutraceuticals properties, generally produced from the species named Arthrospira platensis, and Arthrospira maxima. Arthrospira species were cultivated throughout the world to fulfil the need of human dietary supplementation. An experimental study was planned to know the effect of spirulina supplementation on serum biochemical profile of Wistar albino rats as model study. Test results clearly denoted that diet planned with spirulina fed rats showed better serobiochemical profile when compared with stock diet and rice based diet. The protein and albumin values were significantly higher in spirulina fed rats. Feed consumption rate is very low in spirulina diet but gained more weight when compared to stock and rice diets, this might be due to high biological value protein in spirulina.

Abstract:
The growth of Spirulina platensis is dependent on culture conditions. This study has established adequate conditions for the quality and quantity production of S. platensis. The effect of sulphate salts nutrition on growth performance and biochemical status of S. platensis was assessed in vitro. Prior to culture, the Paracas strain of S. platensis from SAGRIC pond was analysed in different magnesium sulphate (MgSO4; 0.08, 0.16, 0.32, 0.64 and 1.28 g/L), potassium sulphate (K2SO4; 0.08, 0.16, 0.32, 0.64 and 1.28 g/L) and MgSO4/K2SO4 (0.16/0.00, 0.08/0.08, 0.04/0.12, 0.02/0.14 and 0.01/0.15 g/L) concentrations. Culture media pH, total dissolved solids (TDS) and conductivity rate were monitored. Microscopic analysis revealed sulphate salt concentrations influenced the number of whorls and filaments of S. platensis. K2SO4 (1.28 g/L) produced the highest number of whorls and filaments. Moreover, pH level fluctuated by sulphate treatments. K2SO4 (1.28 g/L) had a pH level of 8.77&plusmn;0.01 (day 5 of culture incubation). TDS and conductivity rate, protein and cysteine contents increased with culture age and K2SO4 concentration in a culture medium. Conversely, negative correlations between protein and cysteine contents were observed, and sugar content decreased. Sulphate salt type and concentrations affected polyphenol oxidase (PPO) and peroxidase (POD) activities. MgSO4/K2SO4 (0.02/0.14 g/L) displayed the best PPO and POD activities. Both enzymes appeared to be negatively correlated to the decreasing sugar content. These results indicate growth performances and biochemical status of S. platensis are significantly improved with the adequate supplementation of sulphate salts (MgSO4 and K2SO4) in culture media.

Abstract:
The protein extraction from the blue-green microalgae Spirulina platensis was carried out using ultrasound-assisted extraction and response surface methodology (RSM) was used to optimise extraction conditions. Extraction yield, total phenolic content, antioxidant activity and in vitro protein digestibility of protein extracts were determined. A three factors Box-Behnken design (BBD) of experiments was employed at pH values of 7, 8 and 9; temperatures of 25, 35, and 45°C; and for durations of 60, 90 and 120 minutes. Based on the RSM analysis, optimum extraction conditions (temperature 45°C, pH 7.46 and time 120 min) were obtained for extraction yield (29.05%), total phenolic content (3.52 mg caffeic acid equivalent/g dw), antioxidant activity (11.32 mg Trolox equivalent/g dw) and in vitro protein digestibility (99.36%). We report the first evaluation of the in vitro protein digestibility of Spirulina platensis and find it to be over 90%. This value is higher than the in vitro protein digestibility values of proteins obtained from other algae and plant species, and, in particular, is greater than that of commercial soybean protein isolate.
