Production and Evaluation of Chitosan from Aspergillus Niger MTCC Strains
Three different Aspergillus Niger MTCC strains (872, 1785 and 2208) were used for the production of chitosan. Multivariate growth mediums in varying incubation periods were analyzed for the production. The produced chitosan was characterized by its physical appearance, moisture content (by means of gravimetric method), percentage of ash and solubility (through the Association of Official Agricu...

متن کاملEvaluation of glucosidases of Aspergillus niger strain comparing with other glucosidases in transformation of ginsenoside Rb1 to ginsenosides Rg3
The transformation of ginsenoside Rb1 into a specific minor ginsenoside using Aspergillus niger KCCM 11239, as well as the identification of the transformed products and the pathway via thin layer chromatography and high performance liquid chromatography were evaluated to develop a new biologically active material. The conversion of ginsenoside Rb1 generated Rd, Rg3, Rh2, and compound K althoug...
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 کاملProduction of Proteolytic Enzymes by a Keratin-Degrading Aspergillus niger
A fungal isolate with capability to grow in keratinous substrate as only source of carbon and nitrogen was identified as Aspergillus niger using the sequencing of the ITS region of the rDNA. This strain produced a slightly acid keratinase and an acid protease during cultivation in feather meal. The peak of keratinolytic activity occurred in 48 h and the maximum proteolytic activity in 96 h. The...
