An amylolytic strain was collected from rotten potato and its activity evaluated. The isolated strain was cultivated for amylase production in shake flasks at 35±2C and the fermentation pattern was studied. Optimum temperature for maximum enzyme synthesis was observed at 35°C, when initial pH of fermentation medium was adjusted to 5.5. Maximum extracellular amylase activity of 7.9 U/mL and the ...

Introduction: Alpha amylases are starch hydrolyzing enzymes that possess high industrial demand. Various strategies have been adopted to enhance cost-effective enzyme production of which utilization agro-industrial waste is very promising. Methodology: In this study two amylase producers Bacillus megaterium and Exiguobacterium auranticum were isolated identified by 16sRNA sequencing their growt...

Extracellular fungal cellulases are key enzymes for the degradation of lignocellulosic biomass. Greater production of these enzymes could reduce the cost of biofuels production. In this study, the basal medium for cellulase production by a Penicillium janthinellum mutant (EU2D-21) in submerged fermentation conditions was optimized using response surface methodology (RSM). Initial studies using ...

The oranges were purchased from the local market of Bela. The orange peel and pulp were subjected to successive extraction with solvents in increasing order of their polarity viz. Acetone, hexane, methanol and distilled water. Orange peel and pulp powder was extracted separately by aqueous extraction. The phenolic content of these samples were studied according to the method described by Folin ...

Aqueous and methanol extract of two medicinal plants of Caesalpinia sappan L. and Mimosa pudica L. were evaluated for their antimicrobial activities against Staphylococcus aureus NCIM 5021, Bacillus subtilis NCIM 2010, Escherichia coli NCIM 2118, Pseudomonous aeruginosa NCIM 5029, Klebsiella pneumoniae NCIM 2707, Proteus vulgaris NCIM 2027, Candida albicans NCIM 3102 and Aspergillus niger NCIM ...

The aim of this study was screening fungi strains, isolated from manipueira (a liquid subproduct obtained from the flour production of Manihot esculenta), for amylases production and investigating production of these enzymes by the strain Aspergillus 6V4. The fungi isolated from manipueira belonged to Ascomycota phylum. The strain Aspergillus 6V4 was the best amylase producer in the screening a...

A new species of Bacillus licheniformis produced extracellular xylanase under submerged fermentation when wheat bran is used as carbon source. The xylan is the most common hemicellulosic polysaccharide in food industry and agricultural wastes, comprising a backbone of xylose residues linked by β-1,4 glycosidic bonds. Bacillus licheniformis has been shown to be a promising organism for enhanced ...

Microbial polysaccharides are of great biotechnological and commercial interest have wide application in the food, cosmetic medicine industries. Exopolysaccharide (EPS) production by yeast Cryptococcus laurentii SD7, isolated from fresh water molluscs, was studied using agro-industrial byproducts as substrates submerged fermentation. The Central Composite Design (CCD) 23 used to study influence...
