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 کاملPolyploidy in fungi: evolution after whole-genome duplication.
Polyploidy is a major evolutionary process in eukaryotes-particularly in plants and, to a less extent, in animals, wherein several past and recent whole-genome duplication events have been described. Surprisingly, the incidence of polyploidy in other eukaryote kingdoms, particularly within fungi, remained largely disregarded by the scientific community working on the evolutionary consequences o...

متن کاملBiotransformation of clovane derivatives. Whole cell fungi mediated domino synthesis of rumphellclovane A.
Here we describe the biotransformation of clovane derivatives by filamentary fungi Pestalotiopsis palustris and Penicillium minioluteum, and the application of the latter to the synthesis and determination of the absolute configuration of rumphellclovane A (2). Methoxyclovanol (1), a growth inhibitor of the phytopathogen Botrytis cinerea, is metabolised by P. palustris to yield rumphellclovane ...
متن کاملWhole-stream nitrate addition aVects litter decomposition and associated fungi but not invertebrates
We assessed the eVect of whole-stream nitrate enrichment on decomposition of three substrates diVering in nutrient quality (alder and oak leaves and balsa veneers) and associated fungi and invertebrates. During the 3-month nitrate enrichment of a headwater stream in central Portugal, litter was incubated in the reference site (mean NO3-N 82 g l ¡1) and four enriched sites along the nitrate grad...
