Microbiological transformations of beta-sitosterol and stigmasterol by a soil pseudomonad.
Fermentation of beta-sitosterol by a soil pseudomonad resulted in the formation of 4-stigmasten-3-one, 4-stigmasten-3-one-6 beta-ol and 5-stigmasten-3 beta, 7 alpha-diol. In case of stigmasterol the metabolites isolated and characterized were 4,22-stigmastadien-3-one, 4,22-stigmastadien-3-one-6 beta-ol and 5,22-stigmastadien-3 beta, 7 alpha-diol.
