Abstract
Disclosed are newly discovered and isolated methylotrophic microorganism strains and their natural and/or artificial mutants which grow well under aerobic conditions in a culture medium in the presence of methane as the major carbon and energy source. The methane-grown microbial cells possess a high content of protein and can be utilized as such as feedstuffs. The methane-grown microbial cells or enzyme preparations thereof are also useful in converting C.sub.1 -C.sub.6 alkanes to alcohols, particularly methane to methanol, C.sub.3 -C.sub.6 alkanes to the corresponding C.sub.3 -C.sub.6 sec. alcohols and methyl ketones, C.sub.3 -C.sub.6 sec. alcohols to the corresponding methyl ketones, cyclic hydrocarbons to cyclic hydrocarbyl alcohols (e.g., cyclohexane to cyclohexanol) C.sub.2 -C.sub.4 alkenes selected from the group consisting of ethylene, propylene, butene-1 and butadiene to 1,2-epoxides, styrene to styrene oxide, and converting other oxidizable substrates to oxidized products. The newly discovered and isolated methylotrophic microorganism strains may be aerobically grown on a plurality of methyl-radical donating carbon-containing compounds, such as methanol, methylamine, methy…
