提高木聚糖酶活力和产率 ,降低生产成本是木聚糖酶工业化应用的关键问题。目前以调控培养基初始ｐＨ值、提高木聚糖酶活力的研究报道尚不多见。探讨培养基三种初始ｐＨ值对木聚糖酶合成的影响。培养基初始 ｐＨ值对木聚糖酶的合成有重大影响 ,低 ｐＨ有利于提高木聚糖酶活力。 Increasing xylanase activity and yield and reducing production cost are the key problems in the industrialization of xylanase. At present, there are few reports about the regulation of the initial pH of media and the increase of xylanase activity. The effects of three initial pH values ​​on the xylanase synthesis were investigated. The initial pH value of the medium has a significant effect on the synthesis of xylanase, and the low pH helps to improve the xylanase activity.
