摘　　要：为提高硫酸盐还原菌B13菌株的硫酸盐转化能力,采用正交实验对主要培养基组分和培养条件进行了优化.结果表明:(1)影响B13菌株硫酸盐转化性能的主要因素是碳源含量和培养温度;(2)培养基组分和培养条件经优化后,B13菌株的硫酸盐转化率高达88.49%,硫酸盐转化能力大大提高.In order to improve sulfate-reducing bacteria strain B13＇s sulfate biotransformation capacity, the main culture medium composition and culture conditions were optimized by orthogonal test method. The experimental result shows that：（ 1 ） Carbon content and temperature are the main factors which affect the performance of B13 strain; （2） After the optimization of components of germ medium and and conditions of seed culture, the sulfate biotransformation efficiency of strain B13 reached 88.49%, sulfate biotransformation capacity improved greatly.
