[Monosaccharide composition of the exopolysaccharides of oligonitrophilic bacteria]. 1977

L V Kosenko, and I Ia Zakharova, and N N Mal'tseva, and L M Ivanitskaia

Exopolysaccharides from ten strains of oligonitrophilic bacteria were found to contain galactose, glucose and mannose. Strains belonging to the genus Mycobacterium contained also fucose, ramnose and three sugars that had not been identified: two of them were lipophilic and one had a lower Rf than ramnose. A correlation has been established between the composition of monosaccharides, their molar ratios in exocellular polysaccharides of oligonitrophilic bacteria, and the taxonomy of these microorganisms. Sporeforming bacteria belonging to the genus Bacillus produce polysaccharides which contain galactose, glucose and mannose at a ratio of 10:19: : (13--15). The molar ratio between the same sugars in exopolysaccharides of bacteria belonging to the genera Pseudomonas and Azotomonas is 10:(12--19) : (4--6). The ratio between galactose, glucose, mannose, fucose, ramnose, the unknown sugar and the sum of two lipophilic sugars in exocellular polysaccharides of the genus Mycobacterium is 10:(15--16) : (5--6) : (7--10) : (0.1--9) : (0.3--0.5) : (0.4--0.8).

UI	MeSH Term	Description	Entries
D008358	Mannose	A hexose or fermentable monosaccharide and isomer of glucose from manna, the ash Fraxinus ornus and related plants. (From Grant & Hackh's Chemical Dictionary, 5th ed & Random House Unabridged Dictionary, 2d ed)	D-Mannose,Mannopyranose,Mannopyranoside,D Mannose
D009005	Monosaccharides	Single chain carbohydrates that are the most basic units of CARBOHYDRATES. They are typically colorless crystalline substances with a sweet taste and have the same general formula CnH2nOn.	Monosaccharide,Simple Sugar,Simple Sugars,Sugar, Simple,Sugars, Simple
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
D011549	Pseudomonas	A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in nature. Some species are pathogenic for humans, animals, and plants.	Chryseomonas,Pseudomona,Flavimonas
D002621	Chemistry	A basic science concerned with the composition, structure, and properties of matter; and the reactions that occur between substances and the associated energy exchange.
D005643	Fucose	A six-member ring deoxysugar with the chemical formula C6H12O5. It lacks a hydroxyl group on the carbon at position 6 of the molecule.	Deoxygalactose,alpha-Fucose,alpha Fucose
D005690	Galactose	An aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins. Deficiency of galactosyl-1-phosphate uridyltransferase (GALACTOSE-1-PHOSPHATE URIDYL-TRANSFERASE DEFICIENCY DISEASE) causes an error in galactose metabolism called GALACTOSEMIA, resulting in elevations of galactose in the blood.	D-Galactose,Galactopyranose,Galactopyranoside,D Galactose
D005947	Glucose	A primary source of energy for living organisms. It is naturally occurring and is found in fruits and other parts of plants in its free state. It is used therapeutically in fluid and nutrient replacement.	Dextrose,Anhydrous Dextrose,D-Glucose,Glucose Monohydrate,Glucose, (DL)-Isomer,Glucose, (alpha-D)-Isomer,Glucose, (beta-D)-Isomer,D Glucose,Dextrose, Anhydrous,Monohydrate, Glucose
D001395	Azotobacter	A genus of gram-negative, aerobic bacteria found in soil and water. Its organisms occur singly, in pairs or irregular clumps, and sometimes in chains of varying lengths.
