Abstract
A fermentation process for the production of microbial biomass and a heteropolysaccharide biopolymer using methane as a carbon source. The biomass is suitable for use as a feedstuff and the polymer can be used as a thickening agent e.g. in foods or in the oil industry for use in drilling muds and to assist the recovery of subterranean deposits of oil. The process comprises cultivating at least one strain of a methane utilizing and extracellular heteropolysaccharide biopolymer forming bacterium of the group Methylomonas in a broth comprising an aqueous nutrient medium and a utilizable nitrogen source in the presence of a gas containing methane as a carbon source and a gas containing free oxygen and recovering biomass and heteropolysaccharide biopolymer from the cultivated broth.
