CHEMICAL ANALYSIS OF THE CAPSULAR SUBSTANCE OF CRYPTOCOCCUS-NEOFORMANS

[摘要] A method was descr. for isolation of the capsular polysaccharide from C. neoformans. Capsular material isolated by this procedure contained no starch, glycogen, amino acids, protein, amino sugars or nucleic acid contaminants. The polysaccharide is composed of hexuronic acid 6.7% expressed as glucuronic acid, hexose 18.1% expressed as glucose, and pentose 31.0% expressed as arabinose. It contains neither hyaluronate nor mucoitin sulfate.
