Abstract
A process is disclosed for the microbiological production of ketones from C.sub.3 -C.sub.6 secondary alcohols by contacting C.sub.3 -C.sub.6 secondary alcohols under aerobic conditions with resting microbial cells derived from a microorganism of enzyme preparation derived from said cells, wherein the microorganism has been previously grown under aerobic conditions in a nutrient medium containing a methyl-radical donating compound. Typical methyl-radical donating compounds are: methane, methanol, dimethyl ether, methylamine, methyl formate, methyl carbonate, ethanol, propanol, butanol, etc. Isolation and purification of a novel C.sub.3 -C.sub.6 secondary alcohol dehydrogenase enzyme is also disclosed.
