Biotransformation of Progesterone by Whole Cells of Filamentous Fungi Aspergillus brasiliensis
Microbial steroid biotransformation have found wide-reaching application for the production of more precious and functionalized compounds due to their high regio-and stereoselectivity. In this study, the possibility of using filamentous fungi Aspergillus brasiliensis cells in the biotransformation of progesterone (I), a C-21 steroid hormone was studied for the first time.The fungal strain was i...

متن کاملSolid State Fermentation for Production of Chitosan by Aspergillus Niger
The effect of Solid State Fermentation (SSF) on Chitosan production by A. niger was investigated. A. niger BBRC 20004 from Biochemical and Bioenvironmental Research Centre of Sharif University of Technology (Tehran, Iran), was grown on corn residue. Chitosan was extracted from the fungal mycelia using hot alkaline and acid treatment. A. niger was incubated for 12 days on corn residue with moist...
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. ...
متن کاملNew pathway for nonphosphorylated degradation of gluconate by Aspergillus niger.
A new nonphosphorylative pathway for gluconate degradation was found in extracts of a strain of Aspergillus niger. The findings indicate that gluconate is dehydrated into 2-keto-3-deoxy-gluconate (KDG), which then is cleaved into glyceraldehyde and pyruvate. 6-Phosphogluconate was not degraded under the same conditions. In addition, KDG was formed from glyceraldehyde and pyruvate. Very weak act...
