Abstract: | The rate and extent of stereoselective reduction of 1,3-dioxo-2-methyl-2-(3′-oxo-6′-carbomethoxyhexyl)-cyclopentane to form the 1β-hydroxy-2β-methyl isomer by cultures of Schizosaccharomyces pombe ATCC 2476 was dramatically increased by addition to the fermentation of certain α,β-unsaturated ketones and allyl alcohol. |
