monooxygenation of the monoenoic fattyacids depending on the ethylenic double bond (C═C) configuration. When the double bond was in cis-configuration, an epoxy fattyacid was found to be the major product and two allyl-hydroxy fattyacids were found to be the minor products. But when the double bond was in trans-configuration the product distribution was reversed. The oxygenation efficiency was found to be

AbstractPseudomonas sp. 32T3, a newly identified strain originally isolated from a vegetable oil‐contaminated soil, produces three monohydroxy acids—(E)‐11‐hydroxy‐9‐octadecenoic acid, (E)‐10‐hydroxy‐8‐octadecenoic acid, and (E)‐9‐hydroxy‐10‐octadecenoic acid—as bioconversion products of oleic acid. The bacterial cells were grown in a mineral medium containing oleic acid as the main carbon substrate. The compounds were identified as the corresponding methyl esters on the basis of their chromatographic and spectroscopic (1H and 13C nuclear magnetic resonance and gas chromatography‐mass spectrometry) features.
