Effect of culture conditions on Mycobacterium cyaneum growth and the formation of extracellular polysaccharide

The source of carbon and nitrogen as well as pH of medium influence the possibility of synthesis of the exocellular heteropolysaccharide of Mycobacterium cyaneum and the quantitative harvest of glucan but not its monomer composition. The conditions of mycobacterial growth and glucan synthesis usually do not coincide.
