Abstract:

Detergent enzymes are currently vital and important ingredients of modern powder and liquid detergents. They catalyze various biochemical processes intra-or extracellularly in the detergent industries. Microorganisms are the favored source of detergent compatible fungal amylases compared to plant or animal sources. Detergents cannot be produced in the developed countries without a mixture of detergent enzymes supplementation because they are essential components in the detergent industries. In countries under development, various produced detergents do not have enzymes. Amylases, proteases, pectinases, lipases, mannanases, and cellulases are generally the hydrolytic enzymes used in the detergent industries. They remove all soft, tough and stubborn starchy food, protein, pectin, fatty, mannane and cellulose-based stains attached to the various substrates like fabrics or glassware. A number of review articles on detergent-compatible bacterial and fungal enzymes exists, but none specifically covers detergent-compatible fungal amylases. In the present review, production and aspects of detergent fungal amylases are discussed with an emphasis on the stability of fungal amylases in the presence of detergent constituents. The article will help other worldwide research to study the properties of detergent pectinases and mannanases which are not extensively studied.

Abstract:

Background: Commercial detergents are chemical formulations designed to dissolve or disperse grease, grime, and dirt by making them water soluble or suspending it in water. They are best known for their wide use in laundry industry and household cleaning. After use, the wash waters along with the residual detergents are discharged into sewage system and are carried to water bodies, which result in damaging the biodiversity of aquatic environment due to the non-degradable nature of the active detergent matter present in these cleansing agents.Method: A critical analytical study was conducted on the quality of popular detergent powders sold in the Indian market viz. Ariel, Surf Excel, Rin and Tide with respect to their moisture content, active and total alkalinity, active detergent matter, water-insoluble matter, oxygen releasing capacity and pH. Two natural cleansing agents viz. Areetha and Shikakai were tested for the same parameters. Bacterial cultures were isolated from detergent-rich soil in Dhobighat, Mumbai and used to study detergent degradation over a period of time. Methylene Blue Photometric Assay was used to estimate the reduction in active detergent matter.Result and Conclusion: Areetha and Shikakai were found effective as detergents but with certain limitations. Degradation was seen in the commercial detergents over a period of time.

Abstract:

Laundry detergents are chemicals widely used in everyday life, and in numerous industry branches. In order to perceive the radiological aspect of environmental pollution by wastewater, the analysis of laundry detergents available on the Serbian market was undertaken. Laundry detergent samples were measured by means of gamma spectrometry and the results are presented in this paper. Analysis of the obtained activity concentrations showed that laundry detergents in Serbia mostly fulfill the international recommendation and requirements regarding the phosphate content. Besides that, the content of the detected radionuclides in laundry detergent samples indicates the minor radiological risk to the environment via wastewaters.

Abstract:

In detergent industry, enzymes are used enormously in terms of quantity and economic value. Lipase catalyzes the hydrolysis of triglycerides into diglycerides and monoglycerides by releasing fatty acids. Lipase is produced by bacteria, fungi, and yeasts. This study aims to determine the potential of Alcaligenes faecalis lipase for its application as biodetergen, through stability testing of its lipase activity against detergent components by exposing the enzyme to the commercial detergents, as well as performance testing through washing. Alcaligenes faecalis lipase was produced using Luria Bertani (LB) culture medium supplemented with 1% olive oil inducer. Production is carried out for 24 hours, and the enzyme was harvested at the 18th hour. The harvested enzyme was tested for their stability after being exposed to commercial detergents at a concentration of 1-5%. Results showed that the exposure to the detergents decreased the enzyme activity to 22, 38, 48, 68 and 90%. Performance test showed that the olive oil impurity removal from the fabric was 29%.Keywords: Alcaligenes faecalis Lipase, biodetergent, lipase activities, washing test AbstrakPada industri detergen penggunaan enzim sangatlah besar baik secara jumlah maupun nilai ekonomi.

Abstract:

Alkaline protease is one of the most important industrial enzymes which are excessively used in the detergent industry, food industry, feed industry, pharmaceutical industry, leather industry, etc. 60% of the produced alkaline protease is consumed by the detergent industry alone. In the present study, bacterial isolates that can produce alkaline protease for purpose of bio-detergent were screened among the isolates isolated from kinema (an alkaline fermented food of eastern Nepal). Selected bacterial isolates were further screened for hemolysis activity and the production of other hydrolytic enzymes. Four bacterial isolates selected were tested for their capacity to produce alkaline protease in five different fermentation mediums. Isolate BKHE produces a high amount of alkaline protease (0.4705 ± 0.035 U/mL/min) in fermentation medium M2 (sucrose, 11 g/L; yeast extract, 5 g/L; and KNO3, 5.2 g/l, pH 9). The selected isolate was identified as Bacillus amyloliquefaciens BKHE based on 16S rRNA sequencing and phenotypic features. This bacterial strain was also found to be thermotolerant (confluent growth at 50°C) and salt tolerant up to 10% NaCl concentration. With its versatile ability, bacterial isolate or purified enzymes have potential applications in the food and detergent industry.

Abstract:

The potential application of fungus Trichoderma harzianum Rifai in biodegradation of commercial detergent (MERIX, Henkel, Serbia) was in the focus of this study. The fungus was isolated from wastewater samples of the Rasina River, downstream where the industrial wastewaters of factory Henkel (Krusevac, Serbia) discharge into river. The fungus was cultivated in liquid growth medium by Czapek with addition of detergent at a concentration of 0.3% during 16 days. Analysis of fermentation broth evaluated the chemical and biochemical changes of pH, redox potential, activity of alkaline and acid invertase as well as activity of alkaline protease. In addition, the influence of detergent on fungal growth and total dry weight biomass was determined. At the same time, detergent disappearance in terms of methylene blue active substances in the medium was measured. The detergent at a concentration of 0.3% influenced significant decrease of pH value and increase of redox potential. The detergent showed inhibitory effect on acid invertase activity and stimulatory effect on alkaline invertase and protease activity. The fungus decomposed about 74.24% of tested detergent during 16 days, but total dry weight biomass reduced about 20% in relation to control.

Abstract:

The growth of laundry services is directly proportional to the use of detergent. Detergent is a cleaning product that contains high levels of COD and phosphate. One method that can be used to overcome this problem is Multi Soil Layering (MSL). This research focussed on the flow rate's effect on decreasing pH, COD, and phosphate levels in industrial laundry waste. MSL was installed using a mixture of andosol soil and activated charcoal from coconut shells. Laundry wastewater was let into MSL with flowrate: 10, 50, and 100 ml/minute. The waste degradation system is placed anaerobically by optimising the anaerobic process in the andosol soil. The pH, COD, and phosphate levels were achieved at 7, 90.9%, and 80.7% by draining the laundry industry waste into the MSL system. This MSL method has a residence time of 266 minutes for a flowrate of 100 mL/minute, 532 minutes for a flowrate of 50 mL/minute and 2660 for a flowrate of 10 mL/minute.

Abstract:

Safechem Industries was the leading manufacturer of detergents and allied products in Eastern India under the brand name of ‘SAFED’. Safed had local factories to service the eastern market at a lower cost than other organized players and this also enabled it to compete with the unorganized sector, especially in the rural markets. The case presents a situation in which the General Manager for Marketing & Strategy at Safechem Industries had to formulate the marketing and growth strategy for the future. The company is based mainly in rural parts of Eastern India. The case describes the detergent industry in India with a special focus on rural markets. It also elaborates on the strengths and weaknesses of Safechem with respect to the detergents market and the strategies adopted by it. The General Manager is expected to choose an appropriate marketing and strategic option to help the company achieve its growth plan.

Abstract:

Enzymes have wide applications in detergent industry from early 1900’s. Mostly, clothes are soiled by protein based grime. Most of the detergents have either amylase / protease. Various sources were scrutinized for potent protease activity and Betel leaves were selected, the enzyme was then isolated, purified to homogeneity by ammonium sulphate precipitation, DEAE-Cellulose and gel permeation chromatographic techniques. The enzyme was monomeric in nature with a molecular mass of 38kDa as determined by native PAGE and SDS-PAGE. The enzyme shows maximum activity at 60oC and pH 4.0. The Km and Vmax of the enzyme were 4x10-3M and 54µmol/min/mg respectively. The enzyme was categorically inhibited by PCMB and iodo-acetamide suggesting it to have papain like nature. The stability of the enzyme is assessed over the stretch of alkaline pH and temperature. This evaluation validates the stability of the enzyme and its use in detergent formulations. It was evident that after adding the enzyme preparation the stains (tea, chocolate, blood) were removed much better than that of the controls, which affirms that papain like enzyme from betel leaves, enhances detergent activity.

Abstract:

In light of regulatory considerations, there are ongoing efforts to identify Triton X-100 (TX-100) detergent alternatives for use in the biological manufacturing industry to mitigate membrane-enveloped pathogen contamination. Until now, the efficacy of antimicrobial detergent candidates to replace TX-100 has been tested regarding pathogen inhibition in endpoint biological assays or probing lipid membrane disruption in real-time biophysical testing platforms. The latter approach has proven especially useful to test compound potency and mechanism of action, however, existing analytical approaches have been limited to studying indirect effects of lipid membrane disruption such as membrane morphological changes. A direct readout of lipid membrane disruption by TX-100 detergent alternatives would be more practical to obtain biologically relevant information to guide compound discovery and optimization. Herein, we report the use of electrochemical impedance spectroscopy (EIS) to investigate how TX-100 and selected replacement candidates—Simulsol SL 11W (Simulsol) and cetyltrimethyl ammonium bromide (CTAB)—affect the ionic permeability of tethered bilayer lipid membrane (tBLM) platforms. The EIS results revealed that all three detergents exhibited dose-dependent effects mainly above their respective critical micelle concentration (CMC) values while displaying distinct membrane-disruptive behaviors. TX-100 caused irreversible membrane disruption leading to complete solubilization, whereas Simulsol caused reversible membrane disruption and CTAB induced irreversible, partial membrane defect formation. These findings establish that the EIS technique is useful for screening the membrane-disruptive behaviors of TX-100 detergent alternatives with multiplex formatting possibilities, rapid response, and quantitative readouts relevant to antimicrobial functions.

Abstract:

The objective of this research was to evaluate the effect of three concentrations (3, 6, and 9%) of forage turnip (Raphanus sativus) and physic nut (Jatropha curcas) cakes on dry matter, crude protein, ether extract, neutral detergent fiber, acid detergent fiber, lignin, acid detergent insoluble nitrogen neutral detergent insoluble nitrogen contents, in vitro dry matter digestibility, pH values and concentrations of N-NH3 in elephant grass silages. It was used an entirely randomized design in factorial arrangement [(2×3)+1]. Experimental PVC silos were used and ensiled material was kept for 62 days. The addition of cakes increased the dry matter contents (P<0.05). The fibrous fractions were reduced (P<0.05) with the inclusion of cakes during the grass ensilage and the CP contents increased (P<0.05). The forage turnip cake provided the same pH and N-NH3 values in ideal levels and the physic nut, added to 9%, increased those values (P<0.05). IVDMD was reduced (P<0.05) when the cakes were added. These co-products can be used in small amounts for elephant grass ensilage in order to provide improvement in chemical and fermentation characteristics of the silages. Nevertheless, physic nut cake shows limitations for its use in animal feeding due to the presence of toxic compounds, making necessary studies for their identification and elimination.

Abstract:

Enzymes are the keystone for metabolism or the chemical reactions in biological systems. They help to build certain substances and break others down. Enzymes play a critical role in our bodies, industries and corporate sectors. Protease is an enzyme that helps break the peptide bonds present in the protein and separates the amino acids. Microbial proteases are the ones where the bacteria can produce the protease enzyme. Among many industrial enzymes, microbial protease has a versatile role in many fields like laundry, leather preparation, feather degradation, detergent preparation, biocontrol agents, optical lens cleaners, tannery, deproteinization of prawn shell, prevention of putrefaction of cutting oil, food preservatives, chelating agents, fodder additives, removal and degradation of polymeric substances (EPS), removal of hairs in buffalo hide, waste treatment, bioremediation process, reduction of waste-activated sludge and biofilm formation, degumming of silk, cosmetics (to remove glabellar-frown lines), cheese making, Meat tenderization, rehydration of goat skins and reduced water quantity, fibrin degradation, photographic, silver recovery from X-ray films, dairy industry, control harmful nematodes, fruit juice, and bakery, soybean paste, and sauce industry, pulp mills, alcohol production, fish processing wastes, prion degradation. Microbial protease is popularly used in the detergent industry, leather industry, textile industry, food industry, dairy industry, meat processing industry, bakery industry, pharmaceutical industry, etc.

Abstract:

At the enterprises of the radiochemical industry in the world, the task is to clean the technological and research equipment, overalls, and personnel from contamination with radioactive products. This task is especially relevant in case of emergencies, for example, such as an accident at a nuclear power plant in Fukushima, Japan. A review of the deactivation methods currently used is reviewed. It has been shown that the most typical pollutants are mixtures of radionuclides 137Cs, 144Ce, 144Pr, 90Sr, and 239Pu. All these elements are prone to the formation of chelate complexes. Therefore, complexing substances should be an essential component of deactivation solutions that form stable, water-soluble complex compounds with these radionuclides. When creating the recipe, we chose those complexing agents with the most persistent complex compounds with the expected pollutants. For research and testing in real conditions, we have prepared three types of technical detergents of various compositions with the code name MDS for decontaminating various surfaces, equipment, and workwear. The composition of these preparations consists mainly of an optimized mixture of surfactants, complexing agents, corrosion inhibitors, and processing aids. The studies were conducted to evaluate the possibility of using these funds for deactivation of premises, equipment, washing clothes in the Federal Unitary Enterprise "Mayak" and at its branch NIKIET in town Zarechny at Beloyarskyaya Nuclear Power Station in Russia. The effectiveness of deactivation was judged by the amount of residual contamination of the surface of the samples. The deactivating ability of MDS preparations for stainless, carbon steel, and plastic contaminated with β- and α-emitting nuclides was tested. The possibility of using MDS detergents for the deactivation of platinum ampoules stored as radioactive waste was assessed. The possibility of using MDS detergents for the deactivation of fabric materials, including underwear and work clothes, was also evaluated. The tests showed the high efficiency of the developed detergent MDS compared to the existing and currently used deactivation agents.

Abstract:

A continuous research is attempted to fulfil the highest industrial demands of natural amylases presenting special properties. Newα-amylases extracted from stems and leaves ofPergularia tomentosa, which is widespread and growing spontaneously in Tunisia, were studied by the means of their activities optimization and purification. Some similarities were recorded for the two identified enzymes: (i) the highest amylase activity showed a promoted thermal stability at 50°C; (ii) the starch substrate at 1% enhanced the enzyme activity; (iii) the twoα-amylases seem to be calcium-independent; (iv) Zn2+, Cu2+, and Ag2+were considered as important inhibitors of the enzyme activity. Following the increased gradient of elution on Mono Q-Sepharose column, an increase in the specific activity of 11.82-fold and 10.92-fold was recorded, respectively, for leaves and stems with the presence of different peaks on the purification profiles.Pergulariaamylases activities were stable and compatible with the tested commercial detergents. The combination of plant amylase and detergent allowed us to enhance the wash performance with an increase of 35.24 and 42.56%, respectively, for stems and leaves amylases. Characterized amylases were reported to have a promoted potential for their implication notably in detergent industry as well as biotechnological sector.

Abstract:

The protein aggregation is one of the major challenges of the biotechnological industry, especially in the areas of development and commercialization of successful protein-based drug products. The inherent high aggregation tendency of proteins during various manufacturing processes, storage, and administration has significant impact upon the product quality, safety and efficacy. We have developed an interesting protein purification approach that separates the functionally active protein from inactive aggregates using a detergent concentration gradient. The C-terminally His tagged nucleocapsid protein of Crimean Congo Hemorrhagic fever virus (CCHFV) has high aggregation tendency and rapidly precipitates upon purification by NiNTA chromatography. Using the new purification approach reported here, the freshly purified protein by NiNTA chromatography was further processed using a detergent gradient. In this new purification approach the active protein is retained in the low detergent concentration zone while the inactive aggregates are promptly removed by their rapid migration to the high detergent concentration zone. The method prevented further aggregation and retained the RNA binding activity in the native protein despite numerous freeze thaw cycles. This simple approach prevents protein aggregation by rapidly separating the preformed early aggregates and creating the appropriate microenvironment for correctly folded proteins to retain their biological activity. It will be of potential importance to the biotechnological industry and other fields of protein biochemistry that routinely face the challenges of protein aggregation.

Abstract:

Surfactants, detergents or tensides are synonyms for substances that, even at low concentrations, can drastically alter the interfacial properties of a multiphase system. Their main application fields—among many others—are cleaning processes in households, trade and industry. A certain substance-specific concentration (c.m.c.) is generally considered to be optimal for these applications. However, the fast and inexpensive determination of tenside concentrations is still a difficult task. Our approach to this problem is based on the fact that the draining behaviour of aqueous solutions on hard surfaces depends strongly on the actual concentration of detergents. Near the critical micelle concentration a stable fluid film remains on the wetted surface. The use of optic-intrinsic sensors in the NIR allows the detection of these changes in a straightforward manner by monitoring the sensor response after retrieving the sensor from the sample liquid. A potential application of this sensor principle is expected for controlling the detergent addition mainly in large-scale cleaning devices. This would be of both economical and ecological advantage.

Abstract:

An antigenic glycosylated cysteine protease has been purified from the latex ofEuphorbia nivuliaBuch.-Ham. It exhibits remarkable protease activity in the presence of metal ions, oxidizing agents, organic solvents, and detergents. This enzyme showed potential role in leather processing industry due to its dehairing activity for animal hide without hydrolyzing fibrous proteins, producing, by this way, a better quality product. The enzyme can also be used for silver recovering from X-ray plates. In addition, the stability (temperature and surfactants) and hydrolysis of blood stain data also revealed its application in detergent industries. Agriculturally, this protease finds application in biocontrol process against the infectious management of root knot nematode,Meloidogyne incognita. Biologically, it shows noticeable wound healing, haemostatic and antibacterial activity.

Abstract:

An increased need by the green industry for enzymes that can be exploited for eco-friendly industrial applications led us to isolate and identify a unique protease obtained from a proteolytic Bacillus megaterium-TK1 strain from a seawater source. The extracellular thermostable serine protease was processed by multiple chromatography steps. The isolated protease displayed a relative molecular weight (MW) of 33 kDa (confirmed by zymography), optimal enzyme performance at pH 8.0, and maximum enzyme performance at 70 °C with 100% substrate specificity towards casein. The proteolytic action was blocked by phenylmethylsulfonyl fluoride (PMSF), a serine hydrolase inactivator. Protease performance was augmented by several bivalent metal cations. The protease tolerance was studied under stringent conditions with different industrial dispersants and found to be stable with Surf Excel, Tide, or Rin detergents. Moreover, this protease could clean blood-stained fabrics and showed dehairing activity for cow skin with significantly reduced pollution loads. Our results suggest that this serine protease is a promising additive for various eco-friendly usages in both the detergent and leather industries.

Abstract:

The purpose of this paper is to investigate the relationship between a firm’s capital structure (i.e., leverage) and its operating environment, taking into account firm (i.e., efficiency, asset structure, profitability, size, age and risk) and industry effects. For a sample of Greek pharmaceutical, cosmetic and detergent (PCD) enterprises, firm efficiency was estimated using bootstrapped data envelopment analysis (DEA), and a leverage model was produced using ordinary least squares (OLS) regression. The findings confirm the significance of firm efficiency (i.e., the franchise-value hypothesis over the efficiency-risk hypothesis) and asset structure on leverage. Efficiency and overall and short-term leverage have a significant negative relationship, indicating that more efficient firms tend to choose a relatively low debt ratio. Pharma firms are more affected since they are less efficient than cosmetics and detergents firms. Furthermore, asset structure and short- and long- term leverage have a significant negative and positive relationship, respectively, indicating that the firms with more tangible assets have less short-term debt and more long-term debt in their capital structure. Cosmetic and detergent firms, which have slightly more tangible assets than pharma firms, appear to be able to substitute high-cost, short-term debt with the low-cost, long-term debt by using such assets as collateral.

Surfactants are widely used in industrial products, such as daily chemicals, light industry etc., and it’s very important to separate and analyze the surfactants for development and quality control for those industrial products. In this study, separation and analysis of the surfactants in a detergent were carried out by combined chemical and instrumental approaches systematically. The results indicate that LAS (Linear Alkylbenzene Sulphate) and AES (Alcohol Ether Sulphate) surfactants are identified in the target detergent. This study will supply a practical methodology which can separate and analyze the surfactants in industrial products exactly.

Abstract:

The emerging packaging industry trend of focusing on packaging sustainability is also occurring in the laundry detergent industry. This study presents a cradle-to-grave comparative life cycle assessment (LCA) of three different packaging systems for liquid laundry detergent: the conventional pourable bottle, polyethylene terephthalate (PET) container with pods, and flexible pouch with pods. The scope of this study included material production, intermediate processes, transportation, and end-of-life phases of each packaging system. The results showed that the conventional pourable bottle made of high-density polyethylene (HDPE) has less environmental impact than the other two packaging systems in all impact categories, except ecotoxicity, due to the higher amount of packaging material required to produce the pods. The rigid PET container with pods impacted the environment in all categories more than the multi-layered flexible pouch containing pods, due primarily to the amount of material production, heavier weight, and intermediate processing using injection molding.

Abstract:

Thermo-alkaline stable lipase producing B. coagulans was isolated and identified by 16S rRNA sequencing. The lipase production was optimized using different growth parameters. The enzyme was purified and characterized in terms of pH, temperature, solvents, heavy metal ions and inhibitors. Compatibility with commercially available detergents was also studied. The isolate showed maximum lipase production at 37 ⁰C; pH of 9 within 48 h. Addition of magnesium chloride increased lipase production. Sephadex G-100 chromatography was used to purify lipase. The enzyme showed maximum activity at pH 8 of 30 ⁰C. Lipase form B. coagulans was active at a wide range of temperature between 30-70 ⁰C. It was stable in most of the solvents at a concentration 5 and 10%, except dimethyl sulfoxide (DMSO) and methanol. Iodoacetic acid (IAA) and p-chloromercuribenzoic acid (pCMB) had an inhibitory effect on lipase. The lipase was compatible with commercially available detergents that increased the brightness and whiteness of the tested cotton fabrics. Lipase from B. coagulans with alkaline stability at a wide range of temperature has potential application in the detergent industry.
