Isolation and characterization of new cyclohexylacetic acid-degrading bacteria.
Six cyclohexylacetic acid-degrading strains were isolated from soil samples in Japan and identified as members of the genera Cupriavidus (strain KUA-1), Rhodococcus, and Dietzia by 16S rRNA gene sequence analysis. For the first time members of these genera were shown to be capable of degrading cyclohexylacetic acid. A selected strain, KUA-1, which is the first reported Gram-negative organism capable of growth on cyclohexylacetic acid, was identified as a Cupriavidus metallidurans, based on morphologic and physiologic characteristics and its 16S rRNA gene sequence. Metabolite analysis by HPLC-MS indicated that 1-cyclohexenylacetic acid is an intermediate of cyclohexaneacetic acid metabolism in strain KUA-1.
