Open the CIPO recordAbstract From the Canadian patent
The soluble fractions of facultative organisms grown on C1 compounds are capable of oxidizing organic compounds in the presence of a cofactor system comprising NADH2 or NADPH2. The soluble fraction is obtained by aerobically growing the microorganism in a fermentor under continuous gassing with a mixture of a C1 compound and air and, initially, carbon dioxide before harvesting. Preferably the C1 compound is methane. One facultative organism which is useful in the microbiological oxidation of oxidizable organic substrates is Methylobacterium organophilum (CRL.26 NRRL B-11,222). This newly discovered and isolated methylotrophic microorganism strain and its natural and/or artificial mutants …
