Cell Wall Glucans of the Yeast and Mycelial Forms of Paracoccidioides brasiliensis

AUTOR(ES)
RESUMO

Glucans were isolated from the cell wall of the yeast (Y) and mycelial (M) forms of Paracoccidioides brasiliensis. The alkali-soluble glucan of the Y form had properties of α-1,3-glucan. The alkali-insoluble glucan of the M form was identified as a β-glucan which contains a β-(1 → 3)-glycosidic linkage by infrared absorption spectrum, by effect of β-1,3-glucanase, and by partial acid hydrolysis. The alkali-soluble glucans of the M form were a mixture of α- and β-glucans and the ratio of α- to β-glucan was variable, depending on the preparations.
