Abstract

Xylose oligomers rapidly induced xylanase activity of Trichoderma longibrachiatum, whereas induction was delayed in the presence of glucose. Cellobiose, cellopentaose, and xylobiose did not induce detectable levels of cellulase activity. However, mixtures of xylobiose with cellobiose or cellopentaose rapidly induced cellulase activity. In addition, mixtures of xylobiose with cellopentaose or cellobiose induced xylanase activity more effectively than xylobiose alone. Both xylanase and cellulase activity were detected after a lag period in the presence of lactose.

摘要

木糖寡聚物能迅速诱导长枝木霉的木聚糖酶活性,而在葡萄糖存在的情况下诱导作用会延迟。纤维二糖、纤维五糖和木二糖不会诱导出可检测水平的纤维素酶活性。然而,木二糖与纤维二糖或纤维五糖的混合物能迅速诱导纤维素酶活性。此外,木二糖与纤维五糖或纤维二糖的混合物比单独的木二糖更有效地诱导木聚糖酶活性。在乳糖存在的情况下,经过一段延迟期后可检测到木聚糖酶和纤维素酶活性。
