| 摘 要： | 研究了供氧光照、奥克托今(HMX)初始浓度、接种量、p H值和温度对驯化球形红细菌(Rhodobacter sphaeroides)H菌株降解HMX能力的影响,对其降解动力学方程进行了拟合分析。通过改变1个影响因素,固定其它4个条件,确定了球形红细菌降解HMX的最适宜条件。用分光光度计对HMX浓度和球形红细菌细胞生物量进行了测定。结果表明,驯化后的球形红细菌可高效降解奥克托今,球形红细菌H菌株在不同供氧光照条件下均能很好生长并降解HMX,且降解率均达到70%以上,最佳降解条件为光照厌氧。该菌株降解HMX的最适条件为:HMX初始浓度为100 mg·L~(-1)、p H值为7.0、接种量为15%,温度为30℃,在96 h降解率达到最高,为88.9%。球形红细菌降解HMX的过程符合一级反应动力学方程。
