微生物降解对苯二甲酸的培养条件优化

Optimization of Culture Conditions on Terephthalic Acid Degradation by Mmicroorganism

对苯二甲酸降解菌0612进行培养条件优化。结果表明,氮源为尿素,质量浓度为1 400mg/L,对苯二甲酸质量浓度为1 000 mg/L、接种量为4%、温度30～37℃、pH 7、转速为140r/min的时候最适合该菌的生长以及对苯二甲酸的降解。

Terephthalic acid degrading conditions were researched.The results showed that the best nitrogen source was urea,its concentration of 1 400 mg/L,terephthalic acid concentration of 1 000 mg/L,inoculum volume of 4%,temperature 30～ 37 ℃,pH 7,speed 140 r/min.
