Abstract

Disclosed is a process for the microbiological oxidation of C1 -C6 alkanes and cycloalkanes by contacting said C1 -C6 alkanes or cycloalkanes, under aerobic conditions, in the presence of microorganisms or enzyme preparations derived therefrom, wherein said microorganisms have been aerobically grown in a nutrient containing methane. The microorganisms are newly isolated obligative and facultative methylotrophs.
