title: Biotransformation of acyclic monoterpenoids by Debaryomyces sp., Kluyveromyces sp., and Pichia sp. strains of environmental origin.
abstract: Sixty yeast strains, which belong to 32 species of the genera Debaryomyces, Kluyveromyces, and Pichia, and which were isolated from plant-, soil- or insect-associated habitats, were screened for their ability to biotransform the acyclic monoterpenes geraniol and nerol. The aptitude to convert both compounds (from 2.6 to 30.6, and from 2.7 to 29.1%/g cell DW (=dry weight), resp.) was apparently a broad distributed character in such yeasts. Depending upon the substrate used, the production of linalool, alpha-terpineol, beta-myrcene, D-limonene, (E)-beta-ocimene, (Z)-beta-ocimene, or carene was observed. Linalool was the main product obtained from geraniol, whereas linalool and alpha-terpineol were the main products obtained through the conversion of nerol. Yet, differently from nerol, the aptitude to exhibit high bioconversion yields of geraniol to linalool was an apparently genus-related character, whereas the ability to produce other monoterpenes was a both genus- and habitat-related character. The possible pathways of bioconversion of geraniol or nerol to their derivatives were proposed/discussed.
