摘要: 为得到有效水解杜仲角质层的角质酶,通过生物酶法提取杜仲中的活性成分。从病变的杜仲叶中分离出一株能高产角质酶的菌种,鉴定分析证实该菌株是胶红酵母(Rhodotorula mucilaginosa),这是首次从植物病原真菌以外发现产角质酶的酵母菌,并对该菌株发酵产角质酶的条件进行优化。这一发现意义重大,因为酵母菌比植物病原菌安全许多,更利于大规模生产。

Abstract: To get effective enzyme hydrolyze cutin of Eucommia ulmoides corneous layer, the extraction of the biological active compositions within Eucommia ulmoides was done using enzymatic hydrolysis. This article from the lesion Eucommia leaves isolated bacteria capable of producing cutinase and identify the bacteria, confirmed that the strain belongs to Rhodotorula mucilaginosa, and the strain producing cutinase fermentation conditions were optimized. This finding is significant, because the yeast more secure than plant pathogens is more suitable for mass production.
