Abstract
In vitro subculturing of the yeastlike form of Paracoccidioides brasiliensis strain IVIC Pb9 leads to the disappearance of alpha-1,3-glucan as a main component of its cell wall. However, the addition of fetal calf serum to the growth medium induces the synthesis of this polysaccharide. It is suggested that the synthesis of alpha-1,3-glucan in the cell wall of the yeastlike form of P. brasiliensis is induced by external factors.
摘要
巴西副球孢子菌IVIC Pb9菌株酵母样形态的体外传代培养会导致α-1,3-葡聚糖作为其细胞壁主要成分消失。然而，向生长培养基中添加胎牛血清会诱导这种多糖的合成。有人提出，巴西副球孢子菌酵母样形态细胞壁中α-1,3-葡聚糖的合成是由外部因素诱导的。
