Various fractions were extracted from cell-wall material of Eupenicillium crustaceum, Penicillium brevi-compactum, P. decumbens, Aspergillus flavipes and A. ochraceus. The most characteristic fractions, which may have chemotaxonomic relevance, were F1I, an alpha-(1-3) glucan (alkalisoluble, water-insoluble), which amounted to 16.2-32.5% of the cell-wall material, and F1S (alkali and water-soluble) which represented 2.5-6.2% of the cell-wall material and was identified as a beta-(1-5) galactan. 13C-NMR spectra of the F1S fractions showed the same pattern for all the fungal species, characteristic of beta-(1-5) linked galactofuranose.

UI	MeSH Term	Description	Entries
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
D010407	Penicillium	A mitosporic Trichocomaceae fungal genus that develops fruiting organs resembling a broom. When identified, teleomorphs include EUPENICILLIUM and TALAROMYCES. Several species (but especially PENICILLIUM CHRYSOGENUM) are sources of the antibiotic penicillin.	Penicilliums
D011134	Polysaccharides	Long chain polymeric CARBOHYDRATES composed of MONOSACCHARIDES linked by glycosidic bonds.	Glycan,Glycans,Polysaccharide
D002473	Cell Wall	The outermost layer of a cell in most PLANTS; BACTERIA; FUNGI; and ALGAE. The cell wall is usually a rigid structure that lies external to the CELL MEMBRANE, and provides a protective barrier against physical or chemical agents.	Cell Walls,Wall, Cell,Walls, Cell
D004187	Disaccharides	Oligosaccharides containing two monosaccharide units linked by a glycosidic bond.	Disaccharide
D005936	Glucans	Polysaccharides composed of repeating glucose units. They can consist of branched or unbranched chains in any linkages.	Glucan,Polyglucose,Polyglucoses,Glucan (BO),Glucose Polymer,Polycose,Polymer, Glucose
D001230	Aspergillus	A genus of mitosporic fungi containing about 100 species and eleven different teleomorphs in the family Trichocomaceae.
D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.

D014990	Xylans	Polysaccharides consisting of xylose units.	Xylan
