ABSTRACT
A high efficiency phenol-degrading bacterial strain PS1 was isolated from the drainage ditch of chemical laboratory of East China Institute of Technology.PS1 is a coccus,Gram negative and can live on phenol as its sole carbon and energy source.PS1 to identified as a strain of Raoultella sp.by 16S rRNA gene sequence analysis,which can degrade and tolerate more than 3500mg/L phenol.When phenol concentration is 500mg/L and 1000mg/L,PS1 can completely degrade it in 22 h and 32h,respectively.And while it is between 1500mg/L~3000mg/L,all phenol can be degraded by PS1 in 32h~50h.When phenol concentration is 2500mg/L,the phenol-degrading rate is the biggest and can reach to 78.1mg/h.The optimum growth and phenol-degrading conditions were obtained by orthogonal experiment,which are 25℃,pH6.5,glucose concentration 500mg/L and 20℃,pH7.0,glucose concentration 500mg/L,respectively.
