蒽降解菌T2的最佳培养条件及其对蒽的生物降解动力学研究
Study on optimal cultivating bacteria and its biological conditions of anthracene degrading degrading kinetics to anthracene
摘要
Abstract
A mixed bacteria T2 which used anthracene as the sole carbon source was screened from the long-term petroleum polluted soil. When the inoculation amount of T2, pH, temperature, shaking-bed's speed and the initial concentration of anthracene were 1% , 7, 30℃, 120 r/rain and 100 rag/L, respectively, the degrading rate of T2 to anthracene could reach 56.6% through 5 days' cultivation. The optimal cultivating conditions of strain T2 were obtained through studying the cultivating conditions of T2 , the result showed that when the inoculation amount of T2, pH, temperature and the initial concentration of anthracene were 5% , 6, 35℃ and 40 mg/L, respectively, the strain grew best. In addition, the degrading kinetics experiment of strain T2 to anthracene was carried out, the result showed that the residual concentration of anthracene Y(mg/L) and time t (h) was in line with the equation Y=2. 544 e( -0.00275)t.关键词
