Purification and Zymography of lipase from Aspergillus niger PTCC5010
In this study, Aspergillus niger lipase after extraction of medium culture was precipitated with different percentages of acetone and purified by ion exchange chromatography using SP-sepharose HP and Q-sepharose HP. The process of purification of the anzyme was studied by electrophoresis and the molecular weight was detected and determined by Zymography using overlying containing phenol red and...
متن کاملProduction kinetics and characterization of pectinase enzyme from Aspergillus niger
Food grade pectinases from Aspergillus niger are predominantly used as processing aids in industries. In the present investigation, efforts towards standardization for pilot scale production of pectinase enzyme from A. niger were made. The crude enzyme was studied for its kinetics to optimize substrate concentration and processing parameters on the basis of polygalacturonic activity. Km (Michae...
متن کاملBiotransformation of Sucrose by Using Thermostable and Alkaline Fructosyltransferase Enzyme Isolated from Marine Aspergillus Niger
The biotransformation of sucrose to fructooligosaccharides was investigated using the catalytic action of fructosyltransferase originated from marine Aspergillus niger, using whole cell immobilization. The biomass production and enzymatic reaction were carried out in shake flask. A fructosyltransferase enzyme producing fungi locally isolated from sea water from South East cost of India, by usin...
متن کاملPhytochemical Investigation and Cytotoxic Characterization of Bioactive Constituents from Conyza dioscoridis
A follow-up chemical investigation to methanol extract of Conyza dioscoridis (Family Asteraceae) led to the isolation of seven compounds (1-7). The isolated compounds identified as 2-(3,4-dihydroxyphenyl)ethyl-2-O-[6-deoxy-α-Lmannopyranosyl-4-(3,4-dihydroxyphenyl)-2-propenoate]-β-D-glucopyranoside (1), rutin (2), isoquercetin (3), E-caffeic acid (4), gallic acid (5), quercetin (6), β-Sitosterol...
متن کاملCharacterization And Application Of Tannase Produced By Aspergillus Niger ITCC 6514.07 On Pomegranate Rind
Extracellular tannase and gallic acid were produced optimally under submerged fermentation at 37 (0)C, 72 h, pH 5.0, 10 %(v/v) inoculum and 4 %(w/v) of the agroresidue pomegranate rind (PR) powder by an Aspergillus niger isolate. Tannic acid (1 %) stimulated the enzyme production by 245.9 % while with 0.5 % glucose, increase was marginal. Tannase production was inhibited by gallic acid and nitr...
