    摘要: 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, methyl formate, methyl carbonate, dimethyl ether, etc., to produce microbial cells or enzyme preparations capable of aerobically converting C.sub.3 -C.sub.6 linear secondary alcohols to the corresponding methyl ketones.

    摘要: Microorganisms with low nucleic acid content are produced by acid treating of the microorganism. One embodiment relates to the extraction of so treated microorganisms after their separation from the acid treating fluid, using a strong base for the extraction. Another embodiment relates to the neutralization of the acid treating fluid containing nucleic acids prior to the introduction of this fluid into the fermentation zone, the anion of the acid and the metal cation used in the neutralization step forming minerals desirable for the growth medium in the fermentation step.

    摘要: An improved process for the production of a heteropolysaccharide by fermentation of a methanol containing culture medium with a microorganism of Methylomonas mucosa NRRL B-5696 wherein an alkali metal glycerophosphate is incorporated into the culture medium to provide a source of assimilable phosphate. An iron chelating agent selected from the group consisting of the alkali metal and the ferric/alkali metal salts of ethylenediaminetetraacetic acid may be added to the culture medium and N-tris-(hydroxymethyl)methyl glycine may be employed as a buffering agent. The heteropolysaccharide thus produced may be employed in the in vivo form to provide a viscous aqueous solution injected into a subterranean oil reservoir for mobility control purposes.
