Corynebacterium equi IFO 3730, which had been shown to have an enzyme system for oxidizing a wide variety of linear secondary alcohols, gave the corresponding ketones on incubation with cycloalkanols. The bacterium showed an interesting substrate specificity, i.e., although cyclohexanol and cyclododecanol were oxidized smoothly, a large portion of cyclooctanol was recovered unaffected under the same conditions. The stereochemistry of the substrates had a marked effect on this microbial transformation, cis and trans-4-tert-Butylcyclohexanol showed a remarkable contrast, in that the former was oxidized smoothly by C. equi but the latter was little affected.
