Anaerobic degradation of natural monoterpenes by microorganisms was evaluated by using Pseudomonas citronellolis DSM 50332 and enrichment cultures containing nitrate as an electron acceptor. P. citronellolis grew anaerobically on 3,7-dimethyl-1-octanol and citronellol but not on geraniol, nerol, and alicyclic monoterpenes....
