摘    要:以产低温碱性蛋白酶的黄海黄杆菌YS-9412-130突变株SW2-104为培养菌株,进行碳源、氮源、无机盐、起始pH值、培养时间、接种量和接种龄等发酵条件的优化实验。实验结果证明,在以1%葡萄糖为碳源,以3.5%豆饼粉为氮源,无机盐:0.4%Na2HPO4、0.03%KH2PO4、0.02%MgSO4、0.1%Na2CO3、0.2?Cl2,起始pH值7.0,接种12h种龄的种子4%,20℃、250r/min的条件下在旋转摇床中培养36h,菌株产酶活性最高。

关 键 词:黄海黄杆菌 低温碱性蛋白酶 发酵条件 产酶菌

Abstract:The optimization test concerning the fermentation conditions, such as carbon sources, nitrogen sources, inorganic salts, initial pH, culture time, inoculum size, inoculating time etc., is conducted with the culture strain F. yellowsea YS-9412-130-SW2-104,the mutant of YS-9412-130.The result of the experiment shows that the optimum alkaline protease-producing activity is reached after 36h of culturing in a rotary shaker(250r/min) at 20℃, with 1% glucose as carbon source; 3.5% soy bean cake meal as nitrogen source;inorganic salts of 0.4% Na2HPO4, 0.03% KH2PO4, 0.1% Na2CO3, 0.02% MgSO4, 0.2% CaCl2; initial pH of 7; 4% inoculum cultured for 12h.
Keywords:F. yellowsea Low temperature alkaline protease Fermentation conditions
