Biodegradation of synthetic dyes has been proven as the most efficient, eco-friendly and cost-effective alternative for the treatment of textile dyes contaminated waste water. Remazole Navy Blue (RNB), an azo dye used extensively in the commercial textile industry constitutes hazardous recalcitrant, when released in the aqueous environment. In this research, an isolated bacterial strain identified as Bacillus pumilus HKG212 was studied for its potential to decolorize RNB dye. The isolated bacter

Today oligosaccharides are widely used in food, drug and cosmetics production. Enzymatic hydrolysis of polysaccharides is one of the prospective ways of oligosaccharide production. This work studies kinetic regularities of xylan hydrolysis using free and immobilized xylanase enzyme produced by Тrichoderma viride (endo-1,4-D-xylanase, EC 3.2.1.8). The analysis of kinetic regularities and values of rate constants suggests a hypothesis about some peculiarities of the mechanism of xylan hydrolysis

Media composition for Cephalosporin-C acylase (CPC acylase) was optimized using a stepwise strategy. Out of the fifteen nutrients, five key ingredients viz. glucose, beef extract, glutamic acid, adipic acid and sodium chloride were identified for best medium composition by applying Plackett-Burman (PB) statistical design. Results indicated that above factors negatively affects the CPC acylase production i.e. increase in the concentration of these factors decreases the acylase production. The opt

Vinasse is a problem in worldwide and one that is predicted to increase over the years to come. Total phenol and color removal from this type of vinasse was evaluated using an air-pulsed bioreactor inoculated with Trametes versicolor. Batch operation of the bioreactor removed 71% of total phenol, 18% of color and 40% of chemical oxygen demand (COD). Maximum laccase activity achieved was 428 U/L. The air-pulsed bioreactor was subsequently operated in continuous mode for a period of 25 days, remov

The biological treatment of emulsified oils, using bacteria, has gained a lot of attention and its effectiveness has been widely proven. This is a very important process, as emulsified oils are considered a major environmental hazard. However, the produced biomass, i.e., bacteria, does not have any obvious value. One the other hand, if oils can be removed by microalgae, the produced biomass in this case can be readily used to produce lipids, proteins and pigments. The former product can be used

Polyhydroxyalkanoates are biodegradable, linear polyesters produced primarily by bacteria. Present study reports production and characterization of polyhydroxybutyrate from Bacillus cereus isolated from polluted water sample. The study investigated effect of carbon & nitrogen sources and process parameters like incubation time, pH and temperature. The polyhydroxybutyrate was characterized by Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-ray Crystallogr

Lipases are enzymes able to hydrolyze the ester bond of long-chain acylglycerols. This work aimed to investigate the production, optimization and characterization of Fusarium verticillioides lipase and its application on fatty acid production and fat particles hydrolysis. Response surface methodology (RSM) was employed to optimize the production. Adams medium was used in the submerged fermentation, at 30°C for 96h. Sunflower oil and peptone were the best carbon and nitrogen sources. The optimiz

The Pseudomonas sp. GBS.5 cells were immobilized in calcium alginate (2%): PVA (6%) matrix and the carbazole degradation was studied after dissolving the alginate linkages. This matrix was chosen for immobilization based on mechanical stability and immobilized cell viability. The maximum carbazole degradation rate achieved by PVA-alginate immobilized cells was 52.62 ppm h-1 as opposed to 39.06 ppm h-1 by cells immobilized in calcium alginate beads. The effect of cell loading capacity and initial

Thyroid hormones have pervasive effects on growth and development in the fetus, child, and adolescent regulating calorigenesis and metabolic rate throughout the life. The study was made to investigate the levels of free triiodothyronine (fT3), free thyroxine (fT4) and thyroid stimulating hormone (TSH) of euthyroid subjects. The study included 713 male and 2633 female euthyroid subjects of RIMS, Jharkhand, India during December 2013 to November 2014. It has been found that free triiodothyronine

Microbial fuel cells are the bioelectrochemical systems which convert chemical energy of chemical compounds into electricity by catalytic aid of microorganisms. Plant microbial fuel cells are the fuel cells which apply plants in any way to assist electricity generation. In present study, a house plant Epipremnum aureum was used in cathodic chamber of two chamber microbial fuel cell designed to treat wastewater. The performance of plant microbial fuel cell was compared with conventional microbial

In the present study an attempt was made to isolate a novel psychrophilic bacterial strain producing cold active alpha amylase. Among the 16 isolates observed on starch agar plate, six showed zone of hydrolysis on treatment with Gram’s iodine. Out of these 6 isolates, isolate KS-5 gave maximum alpha amylase production. During optimization of production conditions, 6 days old inoculum at a concentration of 0.5% gave maximum production of α-amylase when the inoculated production medium

The aim of wastewater treatment should think beyond water purification to minimize the waste generation as well as the use of non-renewable resources to make the treatment process as sustainable. Currently, microalgae have been utilized in tertiary treatment methods to address water-energy nexus through biofuel production. The present paper focus on the mathematical modeling of microalgal lipid production along with carbon dioxide sequestration potential of open ponds of National Institute of Te

Present study edge on comparative efficacy and in vitro activity of Bos taurus (cow) urine and dung for controlling red rot disease of sugarcane by determining percentage mycelial growth inhibition (MGI) of Colletotrichum falcatum. The study was carried out on nine isolates of Colletotrichum falcatum obtained from, Department of Biotechnology, Uka Tarsadia University. Results showed the percentage inhibition of mycelial growth suppressed and varied greatly with respect to different isolates and
