Enhancement of Lipase Biosynthesis by Aspergillus niger using Gamma Radiation
Lipase biosynthesis optimization, Aspergillus niger ADM 110, Gamma radiation Objectives: The present study describes the isolation, identification and screening of fugal isolates for the biosynthesis of extracellular lipase enzyme. Methodology: Thirteen fungal cultures were isolated from cotton seeds, waste cake of cotton seed oil and spent bleaching earth, samples by serial dilution method. Al...
متن کاملPurification 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 کاملCatalytic Properties of Lipase Extracts from Aspergillus niger
Screening of lipolytic strains using Rhodamine-B/olive oil plate technique allowed the selection of Aspergillus niger MYA 135. Lipase production in submerged culture containing 2 % olive oil was enhanced by more than 50 % compared to basal cultural conditions. Optimal catalytic conditions for olive oil-induced lipase were pH=6.5 and 30–35 °C. These values were shifted to the acid region (4.0–6....
متن کاملSynthesis of malformin by an enzyme preparation from Aspergillus niger.
Yukioka, M. (University of Hawaii, Honolulu), and T. Winnick. Synthesis of malformin by an enzyme preparation from Aspergillus niger. J. Bacteriol. 91:2237-2244. 1966.-An enzyme fraction derived from disrupted Aspergillus cells was able to utilize each of the component labeled amino acids of malformin for the synthesis of this cyclic pentapeptide. The process was stimulated by adenosine triphos...
متن کاملRapid Synthesis of Silver Nanoparticles by a Marine-derived Fungus Aspergillus Niger and their Antimicrobial Potentials
Recently, biosynthesis of nanoparticles has received attention due to an increasing need of developing rapid, simple and ecofriendly protocol. Pathogenicity of some of the organisms and lengthy reaction are the drawbacks involved with biosynthesis. We describe a simple protocol for rapid synthesis of silver nanoparticles through biological route using a marine-derived fungus Aspergillus niger. ...
