[Conditions for extracellular heteroglycan biosynthesis by Mycobacterium salivarium].
Mycobacterium salivarium 76 was found to synthesize the individual exoglycan unbound to proteins and lipids in media containing various sources of carbon (sugars, polyatomic alcohols, n-alkanes) and nitrogen (nitrates and ammonium salts) at pH from 6 to 10. These compounds determined the quantitative yield of glycan, but had no effect on its monomeric composition represented by glucose, mannose, uronic acid and pyruvate residues. The highest yield of biomass and polysaccharide was found in the medium with n-dodecane and KNO3 at pH 7.0.
