【中文摘要】 新分離到一株能產生較高水平菊粉酶的采絨革蓋菌（ＣｏｒｉｏｌｕｓｖｅｒｓｉｃｏｌｏｒＺＱＷ－９６）。通過對培養基組成及培養條件的優化研究發現，用菊芋粉抽提液代替菊粉，氮源為玉米漿，添加０．０４％的吐溫—８０的發酵培養基，在ｐＨ５．８、２４℃、轉速為１５０ｒ／ｍｉｎ，裝液量為７５ｍｌ／５００ｍｌ三角瓶條件下發酵６天后，胞外菊粉酶活性達２．２４ｕ／ｍｌ，比原來提高了１．３倍。關于該菌產菊粉酶的研究，國內外均未見報道
【英文摘要】 Coriolus versicolor strain ZQW-96 with higher inulinase activity was isolated. After studying of the optimal medium composition and culture conditions, we found that the strain's extracellular inulinase activity reached to 2 24u/ml with the medium whose carbon source was the extract of the tuber powder of Helianthus tuberosus instead of inulin, and nitrogen source was corn steep liquor, adding 0 04% Tween-80, and with the culture conditions was pH5 8, 24℃ 150r/min shaking, and six days' fermentation. This enzyme activity was 2 3 times higher than the initial. The report about the strain producing inulinase has never been found.
