Abstract

Endo-1,4-beta-glucanase formation of Penicillium janthinellum was repressed by glucose, sophorose, and glycerol. Chromatography on DEAE-Sephadex A-50 was employed to separate the 1,4-beta-glucanases from two cellobiases. The 1,4-beta-glucanases were inhibited competitively by cellobiose and glucose, and the two cellobiases were inhibited by glucose and glucono-delta-lactone.

摘要

葡萄糖、槐糖和甘油可抑制淡紫青霉内切 - 1,4 - β - 葡聚糖酶的形成。采用DEAE - 葡聚糖A - 50柱层析法从两种纤维二糖酶中分离出1,4 - β - 葡聚糖酶。纤维二糖和葡萄糖对1,4 - β - 葡聚糖酶有竞争性抑制作用,而葡萄糖和葡萄糖酸 - δ - 内酯则对两种纤维二糖酶有抑制作用。
