ABSTRACT:
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.
