酶的诱导 meaning in English
enzyme induction
Examples
- Maximal yields of cellulase were obtained on the relatively undegraded cellulose ( for example , a - cellulose and avicel )
结果发现结构较完整的纤维素类碳源对酶的诱导活性优于其它碳源物质。 - A . niger m - l which was screened in our laboratory produced a strongly a - transglucosidase . in this paper , studies on the fermentation conditions , purification and characterization of a - transglucosidase and its necessary groups was carried out in this dissertation . the main reports were as following : the fermentation conditions in shaking flasks were investigated by the method of single - factor analysis , the suitable main medium was achieved : which contained 4 % a , 2 % b and 1 % g ; the a . niger m - l was inoculated into 100ml medium in flask , shaking in 33 c at 140r / min for four days , with initial ph6 . 5 and 6 % inocula volume ; adding 0 . 1 mmol / l methyl a - d - glucopyranoside had inductive effect on enzyme formation , the a - transglucosidase activity amounted to 296 . 05u / ml
本研究以黑曲霉m - 1为出发菌株，对其-葡萄糖转苷酶的产酶影响因素、纯化、酶学性质以及必需基团进行系统的研究，结果如下：通过对影响黑曲霉m - 1产-葡萄糖转苷酶的单因素分析，得液态发酵生产-葡萄糖转苷酶的最适产酶条件为： 4 a ， 2 b和1 g ；在33 ，起始ph值为6 . 5 ，转速为140r min ，接种量为6 ，装液量100ml条件下，发酵4 . 0d ，酶活力达296 . 05u ml ，添加0 . 1mmol l的酶作用底物甲基- - d -葡萄糖苷对产酶的诱导作用最大。
