Abstract:

Algae Spirogyra peipingensis is a group of green algae from the order Zygnematales. Spirogyra algae serves as a bioremediation agent. In addition Spirogyra algae has great potential in reducing toxin levels in cigarette smoke. Because the biomass of alga Spirogyra has an irregular shaped surface texture and consists of amino acid, amide, carboxylic, hydroxyl, and carbonyl group that can bind various heavy metals and other harmful compounds. Alga Spirogyra peipingensis samples used are algae from Bone, South Sulawesi. Prior to the trial, the first pretreatment and processed to become powder. Algae powder was then applied to cigarette filters and tested on several respondents. Results showed that there was a significant decrease tar, nicotine and carbon monoxide levels in cigarette smoke by using Spirogyra peipingensis algae but the most significant decrease of carbon monoxide, while tar and nicotine decreased even though not as high as carbon monoxide.

Abstract:

The hierarchy of factors that control the growth and biomass of Spirogyra sp. was examined for an 18-km reach of the Daly River in the wet/dry tropics of northern Australia. On an annual temporal scale, hydrological disturbances control Spirogyra. Over the wet season (typically December–April), frequent runoff events prevent the colonisation and growth of Spirogyra in the Daly River. This is followed, however, by a lengthy period (typically May–November) without hydrological disturbances and river velocities that favour benthic algal growth. In 2001, Spirogyra became visible in mid-May, then grew to reach a maximum biomass in early August of 28 mg m−2 of chlorophyll a. The standing crop of Spirogyra was primarily determined by the availability of gravel substrate and the velocity and shear stress at the river-bed. Photosynthetically available radiation (200–800 μE m−2 s−1) reaching the river-bed should not have limited algal growth, though self shading within the Spirogyra mats may have been important. Although the growth rate of Spirogyra was probably limited by nutrients, the maximum biomass was constrained by autogenic sloughing. The biomass of Spirogyra steadily declined to half its maximum in early October despite favourable river velocities, most likely a result of nutrient limitation. Spirogyra was then removed from the river by the first major runoff event of the wet season in late October. The hierarchy of factors that control benthic algal biomass in the Daly River are the same as in lower latitudes, though the long period of favourable river velocities when smaller scale, proximate factors (e.g. nutrients, shear stress) control biomass should be noted.

Abstract:

Abstract In the present study, biosorption behavior of a green filamentous alga, spirogyra in its native and modified states was investigated for copper removal from an electroplating industrial effluent. For this, the effluent containing 194 mg·L−1 Cu2+ in sulfate medium was contacted with both forms of spirogyra, under the parametric variations of effluent pH, adsorbent dosage, contact time, and sorption temperature. The study revealed spirogyra as a prominent candidate for removing contaminant metal cation; however, at the same condition, biosorption capacity of modified biomass in gel form was higher than the native spirogyra. At the optimized condition with 6 g sorbent dosage treated to 100 mL effluent for 30 min at pH 6.0 and temperature 20 °C, the maximum 82.8% and 96.4% copper could be adsorbed by the native and modified spirogyra, respectively. The batch sorption data using native biomass followed pseudo-first-order kinetic; exhibiting the multilayer sorption mechanism via surface diffusion could be defined by the Freundlich model. In contrast, the sulfuric acid treated modified spirogyra followed pseudo-second-order kinetics and intra particle diffusion as the rate-limiting step.

AbstractObjectivesThis study was conducted to evaluate the effects of oral supplementation of Spirogyra algae on oxidative damages and inflammatory responses in streptozotocin (STZ)-induced diabetic rats.MethodsDiabetes was induced by administration of 55 mg/kg of streptozotocin. A total of sixty-four rats were divided into eight groups of eight rats each as follows:1) non-diabetic control; 2, 3, and 4) non-diabetic rats treated with 15, 30, and 45 mg of Spirogyra algae/kg/d; 5) control diabetic; and 6, 7, and 8) diabetic rats treated with 15, 30, and 45 mg of Spirogyra algae extract. At the end of the trial, the serum concentrations of glucose, interleukin-6 (IL-6), tumor necrosis factor-a (TNF-a), malondialdehyde (MDA), glutathione (GSH), total antioxidant status (TAS), C-reactive protein (CRP), insulin, triglycerides, and cholesterol were examined by specified procedures.ResultsOur findings indicated that the administration of STZ significantly increased the serum concentrations of glucose, triglycerides, cholesterol, CRP, IL-6, TNF-a, and MDA and decreased the serum levels of GSH and TAS (P<0.05) in diabetic rats. Oral administration of Spirogyra alleviated adverse effects of diabetes on oxidative stress and inflammatory factors in diabetic rats (P<0.05).ConclusionIt can be stated that Spirogyra algae extract can be used for treatment of diabetes likely due to prevention of oxidative stress and alleviation of inflammation in the rat model.

Abstract:

On the basis of three morphological characters (e.g., filament, width, chloroplast number, and type of cell end wall), six filament types of Spirogyra were collected along Bear Creek in the Santa Catalina Mountains near Tucson, Arizona. The occurrence and distribution of filament types showed seasonal and geographical patterns. Filaments were more frequently collected in early summer from pools at lower elevation. Growth of Spirogyra may be influenced by water temperature, pH, and water amount. Most filaments occurred more abundantly while water temperture and pH were relatively high. The number of filament types was greatest at sites with a semi-permanent water supply rather than in temporary and permanent pools. Of the six types of Spirogyra, Type V showed morphological and genetic changes through vegetative growth and sexual reproduction in a clonal culture in the laboratory. After 33 months culturing, a narrower filament-width group (Group II, 22.0 ± 1.1 μm) was produced in the original clone (Group I, 30.9 (+OR-) 0.7 μm). Groups I and II were homothallic and sexually compatible. Zygospores from the cross of I x II yielded germlilngs of Groups I, II, III (27.2 ± 1.0 μm) and a binucleate IV (44.9 ± 0.8 μm). Chromosome counts were: Group I (24), Group II (12), Group III (18), and Group IV (24, one nucleus). Relative nuclear-DNA fluorescence values increased as filament width and chromosome number increased. Cytologically, Group I is a tetraploid, Group II a diploid, and Group III a triploid. Systematically, Groups I, II and III key out to pirogyra singularis, S. communis, and S. fragilis, respectively, using Transeau's monograph on Zygnemataceae. These species are interpreted to be a species complex of S. communis (whose name has priority) with the ancestral haploid (x = 6) missing. Five years after isolation of the original strain in this species complex filaments corresponding to Groups I and II were found at the original collection site. The two field-collected groups were indistinguishable from the laboratory species complex in morphology and chromosome number. Homothallic conjunction within two field width groups yielded progeny similar to those from homothallic conjunction of groups in the laboratory species complex. Filament widths of progeny were generally within the width limits of respective parental groups. The four intergroup crosses between laboratory and field width groups were successful and yielded progeny representing Groups I, II, and III. The similarities in morphology, chromosome numbers, and reproductive behavior of laboratory and field width groups imply that the laboratory species complex of S. communis has a natural counterpart in the field.

Nowadays, the world energy crisis and environmental issues are in order. So, the use of biofuels has gained an extraordinary importance and microalgae seem to be a promising feedstock, as they do not compete with food either for arable land or for potable water. Also, they produce several interesting compounds such as sugars and lipids. The aim of this dissertation was the study of sugar production by Spirogyra sp. regarding the production of bioethanol. So, the first step was the cultivation of this chlorophyte under continuous lighting and day-night cycles (14 h/10 h), to evaluate the effect of light regime on the growth and sugar accumulation. Methods for cell rupture and sugars extraction were also studied and optimized. A yeast screening towards the production of ethanol from microalgae hidrolysates was the final step of this work. The highest biomass concentration was attained under day-night cycles (0,34±0,05 vs. 0,29±0,02 gL-1) but the greatest sugar accumulation occurred in the presence of continuous illumination (27 vs. 24 % g eqglu.g biomass-1). From all the tested methods for cellular disruption of Spyrogira sp., the most appropriate was acid hydrolysis by sulfuric acid 2 N in autoclave for 30 min (78 % extracted sugars). S. carlsbergensis showed to be the most promising microorganism with conversion yields of 82 % for glucose and mannose. This yeast presented also the ability to use in some extent arabinose, a pentose found in algae hydrolysates.

Abstract:

Este trabalho, desenvolvido no contexto de estágio curricular nos laboratórios de Engenharia Química e Ambiente do Instituto Politécnico de Tomar, teve como principal objectivo estudar a potencialidade de produzir biomassa algal, de forma integrada no processo de tratamento de águas residuais através de zonas húmidas construídas. Neste âmbito, desenvolveram-se actividades predominantemente de foro experimental segundo três vertentes: a implementação ou validação de técnicas analíticas, tais como a determinação da concentração de nutrientes na fase aquosa, o teor de biomassa em termos secos e o teor de açúcares totais e redutores; o estudo da potencialidade de utilização de lixiviados, ricos em nutrientes, obtidos de argilas expandidas usadas como enchimento de zonas húmidas construídas, como meio de crescimento de micro e de macroalgas; a avaliação e tentativa de optimização do crescimento das microalgas e das macroalgas. Escolheu-se a macroalga Cladophora aegagropila atendendo a estar referenciada pela sua capacidade de clarificação das águas. Estudou-se o crescimento da macroalga em substratos tradicionais, e na argila expandida sem qualquer tratamento, verificando-se uma aparente boa adequação das algas a este diferente substrato. Não existindo dados na literatura sobre o teor de açúcares ou amidos nesta alga, determinou-se por análise que o teor em açúcares totais é de 38,8%, dos quais 22,4% são açúcares redutores. Foram também estudadas duas microalgas, Anabaena sp. e Spirogyra sp. Avaliou-se a cinética de crescimento em diferentes meios de crescimento, determinando-se a taxa específica de crescimento e o tempo de duplicação. A concentração máxima obtida foi de 0,21 g/L para a Anabaena sp., sendo de salientar que o meio líquido obtido por lixiviação da argila expandida comprovou ser apropriado para o crescimento das microalgas, apesar de conduzir a taxas específicas de crescimento inferiores. A utilização dos lixiviados pode representar uma redução de custos na produção de algas, e uma forma de regenerar os materiais de enchimento usados nas zonas húmidas construídas

Benthic filamentous (green) macroalgae, mostly Cladophora, and Spirogyra, often spawn profusely during growth seasons; the algae can be found all year around in unpolluted freshwater in Taiwan that has slightly hard water, with adequate flow and low turbidity. In general, the life cycle of algae is short, it can be easily cultivated, and it propagates quickly. The basic structure of green algae cells is similar to those of vascular plants which make them an ideal material to study biochemical reactions and physiological mechanisms of various plants. The current study explores differences in sporophyte and gametophyte generations of Spirogyra in terms of environment, growth seasons, abundance during various growth cycles, and epiphytic algal species. The study uses this perspective to discuss the life cycle of Spirogyra, and to take a look at the relationship of interaction between epiphytic and precursor algae in the lifecycle of Spirogyra; hence, the research on the epiphytic and precursor algae of Spirogyra was conducted concurrently with the study on the lifecycle of Spirogyra. The findings will serve as a basis for biomaterial applications or taxonomically, morphologically, and physiologically-related researches on domestic freshwater Spirogyra.

The purpose of this study is to investigate the adsorption of Methylene Blue (MB) and ADMI (American Dye Manufacturers Institute) from wastewater using Spirogyra (Sp.). Results of kinetic adsorption experiments indicated that the rate of adsorption increased with increasing the concentration of MB and pH; the adsorptive capacity increases with decresing ionic strength. The maximum adsorption capacity of MB increased with increasing temperature, whereupon the adsorption capacity of MB ranged from 6.63×10-5 mol/g to 9.89×10-5 mol/g was determined. Pseudo-second-order (PSO) can be used to describe the kinetic data. The adsorption process was found to be spontaneous and endothermic. The results reveal that the removal efficiency of ADMI is the best with lower pH and higher temperature. In dyes in the entire waste water experiment result to discover, effect of ADMI elimination, has the good result production under the acidic environment. Modified Freundlich equation (MFE) can be used to describe the kinetic data.

Produced by microbial extracellular polymeric substance(EPS) has been regarded as an important renewable resources and technology in recent years, many studies exploring valuable EPS, and has a production potential of algae. Spirogyra spp. is a genus of filamentous green large algae commonly found in fresh water. Under the natural environment, Spirogyra spp. secretes large amounts of EPS and forms a sticky mucilage layer. This study discovered that salinity increases, the amount of EPS increases. By the 13.0 EPS mg / g.fw increased 26.9 EPS mg / g.fw, and incubation time as more than four hours, that influence is not different, but the EPS, polysaccharides in tandem with increased salinity increased significantly, but protein only a slight increase. Therefore, the levels and ratio of protein and polysaccharide in EPS. In Spirogyra spp. to produce extracellular polymeric algae species, can be controled under different salinity.
