Biotransformations of (+/−)-geosmin by terpene-degrading bacteria

Two terpene-degrading bacteria able to transform (+/−)-geosmin have been identified. Pseudomonas sp. SBR3-tpnb, following growth on γ-terpinene, converts (+/−)-geosmin to several products; the major products are ketogeosmins. Rhodococcus wratislaviensis DLC-cam, isolated on d -camphor, also converts...

Zusammenfassung:	Two terpene-degrading bacteria able to transform (+/−)-geosmin have been identified. Pseudomonas sp. SBR3-tpnb, following growth on γ-terpinene, converts (+/−)-geosmin to several products; the major products are ketogeosmins. Rhodococcus wratislaviensis DLC-cam, isolated on d -camphor, also converts (+/−)-geosmin to several oxidation products, primarily ketogeosmins identical to those produced by strain SBR3-tpnb as well as hydroxygeosmins. This conversion appears to be inducible by (+/−)-geosmin and not by d -camphor.
