Microbial transformation of thiocyanate
Environmental Pollution, 1990Thiocyanate is present in appreciable concentration in coal carbonization wastewater along with other toxicants like phenols, cyanide, sulphide and ammonia. This paper encompasses studies on biodegradation of thiocyanate by a microbial consortium obtained from a biological treatment plant receiving coal carbonization wastewater.

Microbial Transformation of Curvularin
Journal of Natural Products, 2005The microbiological transformation of curvularin (1) with Beauveria bassiana ATCC 7159 afforded three new metabolites identified as curvularin-7-O-beta-D-glucopyranoside (2), curvularin-4'-O-methyl-7-O-beta-D-glucopyranoside (3), and 6-hydroxycurvularin-4'-O-methyl-6-O-beta-D-glucopyranoside (4) resulting from hydroxylation, glucosidation, and ...

Microbial Transformation of Sampangine
Journal of Natural Products, 1999Microbial transformation studies of the antifungal alkaloid sampangine (2) have revealed that it is metabolized by a number of microorganisms. Using a standard two-stage fermentation technique, Beauvaria bassiana (ATCC 7159), Doratomyces microsporus (ATCC 16225), and Filobasidiella neoformans (ATCC 10226) produced the 4'-O-methyl-beta-glucopyranose ...

Current Opinion in Chemical Biology, 1998
Although the use of microbial biocatalysts for chemical reactions pre-dates by a considerable margin the application of isolated enzymes for this purpose, considerable progress continues to be made in the use of whole-cell catalysts. The application of whole-cell biocatalysts in oxygenase-catalysed reactions, the reductions of carbonyl and nitro groups,

Microbial Transformation of Benzosampangine
Journal of Natural Products, 2000Microbial transformation studies of the synthetic antifungal alkaloid benzosampangine (1) have revealed that 1 is metabolized by a number of microorganisms. Using a standard two-stage fermentation technique Absidia glauca (ATCC 22752), Cunninghamella blakesleeana (ATCC 8688a), Cunninghamella species (NRRL 5695), Fusarium solani f. sp. cucurbitae (CSIH #

Microbial transformations of glaucine
Journal of the Chemical Society, Perkin Transactions 1, 1977Microbial transformation experiments were conducted with the aporphine alkaloid glaucine. Small-scale screening experiments provided a number of micro-organisms which produced three metabolites. In preparative scale studies, Streptomyces griseus(Ul 1158) produced norglaucine (4) and 2-O-demethylglaucine (6)(predicentrine) in 11 and 14% yield ...

Microbial Transformation of Dehydroepiandrosterone
Natural Product Research, 2003Transformation of dehydroepiandrosterone (DHEA) (1) was carried out by a plant pathogen Rhizopus stolonifer, which resulted in the production of seven metabolites. These metabolites were identified as 3beta,17beta-dihydroxyanandrost-5-ene (2), 3beta,17beta-dihydroxyandrost-4ene (3), 17beta-hydroxyandrost-4-ene-3-one (4), 3beta,11-dihydroxyandrost-4-ene-

Microbial Transformation of Aspidospermine
Journal of Pharmaceutical Sciences, 1975Thirty actinomycetes were isolated from soil samples and screened for their ability to modify the structure of aspidospermine. One actinomycete culture converted aspidospermine into O-demethylaspidospermine but failed to modify N-deacetylaspidospermine, N-ethyl-N-deacetylaspidospermine, 7-methoxyindole, and 7-methoxytryptophan.
