activity amount造句

• 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：4a，2b和1g；在33，起始ph值为6.5，转速为140rmin，接种量为6，装液量100ml条件下，发酵4.0d，酶活力达296.05uml，添加0.1mmoll的酶作用底物甲基--d-葡萄糖苷对产酶的诱导作用最大。
