[Conditions for Exopolysaccharide Biosynthesis by Mycobacterium Mucosum and Its Composition]

Mycobacterium mucosum 32 synthesizes an extracellular heteropolysaccharide during its growth in media with different sources of carbon (sugar, polyatomic alcohols, n-alkenes) and nitrogen (nitrates, ammonium salts) within the pH range from 6 to 10. The yield of the polysaccharide depends on the cultural growth and on several factors of the medium. The monosaccharide composition of the glycan does not change depending on the conditions. It contains glucose, galactose, mannose and uronic acid. This exopolysaccharide is an individual compound which is not bound to proteins or lipids.
