解釋
葡萄糖氮比率-
The xylanase activity of the mutant kept stable after 10 generations. after orthogonal designing experiment, the optimum fermentation conditions of a. niger j 506 were obtained, which is as followed : concentration of the major carbon resource 4 %, ratio between bran and corncob 5 : 5, concentration of glucose 0. 1 %, concentration of ammonium oxalate as supplemental nitrogen resource 2. 0 %, the initial ph of liquid medium 5. 0, 100ml / 250ml flask
經過正交試驗設計,得出突變株a . nigerj506產木聚糖酶最佳的工藝條件為:主碳源濃度4 、麩皮與玉米芯的比例為5 : 5 、輔加碳源葡萄糖的濃度是0 . 1 、輔加氮源草酸銨的濃度是2 . 0 ,培養基初始ph為5 . 0 , 250ml三角瓶的裝液量為100ml 。
