【摘要】 以豆油作为唯一碳源,经过2个月驯化后筛选获得具有高效油脂降解能力的细菌1株,编号为S16,经鉴定为芽孢杆菌。对影响S16降解能力的几个因素进行了初步研究,结果表明,在初始pH为7.0,初始含油量为400 mg/mL,摇床转速为200 r/min,培养温度30℃条件下,该菌株生长旺盛,发酵72 h后对豆油的降解率可以达到73.5%。更多还原

【Abstract】 An effective oil-decomposing bacterial strain S₁₆was obtained by screening after two months’ domesticating,using bean oil as the sole carbon source,and strain identification proved that strain S₁₆ belonged to Baccillus subtilis.The factors affecting the degradation were studied.The results showed that the strain could quickly grow under the condition that the intial oil concentration was 400 mg/L,the intial pH was 7.0,the agitation was 200 r/min,and temperature was 40 ℃.The degrading rate on bean oil reached 73.5% after fermentation.更多还原
