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.

UI	MeSH Term	Description	Entries
D009161	Mycobacterium	A genus of gram-positive, aerobic bacteria. Most species are free-living in soil and water, but the major habitat for some is the diseased tissue of warm-blooded hosts.	Mycobacteria
D011135	Polysaccharides, Bacterial	Polysaccharides found in bacteria and in capsules thereof.	Bacterial Polysaccharides
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D002854	Chromatography, Paper	An analytical technique for resolution of a chemical mixture into its component compounds. Compounds are separated on an adsorbent paper (stationary phase) by their varied degree of solubility/mobility in the eluting solvent (mobile phase).

D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
