摘　　要：以苯酚为唯一碳源,采用逐量分批驯化的方法从活性污泥中筛选分离得到一株高效苯酚降解菌JFJ-2,经鉴定为Diaphorobacter属。JFJ-2菌最高可耐受1800mg·mL-1的苯酚浓度,其最佳降酚条件为:温度30～40℃,pH值7.0～10.0,含盐量低于1.5%,苯酚浓度1000mg·mL-1。Using phenol as sole carbon source,a strain of JFJ-2 with high degradation ability was screened and isolated from active sludge using the way of acclimatization by gradually increasing phenol dosage in batches.The identification suggested that the strain of JFJ-2 belonged to Diaphorobacter.The strain of JFJ-2 could resist to phenol up to 1800 mg·L^-1.The optimum conditions of phenol degradation were as follows：temperature of 30-40℃,pH value of 7.0-10.0,salt content lower than 1.5%,phenol concentration of 100mg·L^-1.
