The relationship between conidial enzymes of Penicillium expansum and spore germination was examined. The activities of xylanase and pectinase, but not of cellulase and amylase, were detected in the conidia. The levels of xylanase and pectinase were greatly enhanced by xylan and pectin as respective carbon sources in the basal medium. No conidia germinated in the basal medium without a carbon source. The type of carbon source and the enzyme levels of the conidia did not affect the rate of germination. However, a relationship was found between the enzyme levels and the elongation of the germ tubes.
研究了扩展青霉分生孢子酶与孢子萌发之间的关系。在分生孢子中检测到木聚糖酶和果胶酶的活性，但未检测到纤维素酶和淀粉酶的活性。在基础培养基中，木聚糖和果胶作为各自的碳源，可大大提高木聚糖酶和果胶酶的水平。在没有碳源的基础培养基中，没有分生孢子萌发。碳源类型和分生孢子的酶水平不影响萌发率。然而，发现酶水平与芽管伸长之间存在关系。
