摘　　要：从污水中通过选择性富集和驯化培养,分离得到两株分别以苯酚、苯胺为惟一碳源的菌株.经初步鉴定这两种菌株均为假单胞杆菌属(Pseudomonas sp.).通过对两菌株在不同温度、pH值以及相应苯酚、苯胺底物浓度下的生长和降解情况的研究,确定了最佳降解苯酚、苯胺的工艺条件为pH 7.0,温度30℃,好氧.当苯酚、苯胺底物浓度不超过1 000 mg/L时,两菌株对其去除率可达到95%以上.Strains selectively screening, utilizing phenol and acclimatizing and sep aniline as the sole arating, respectivel as Pseudomonas sp. The optimum degradation condition of b oxygen, and temperature was 30 ℃. When the concentration ca Y, ot of rbon source were isolated from sewage by both of which were elementarily identified h bacteria was studied： pH was 7.0, fine substrates was below 1 000 mg/L, the removal rate of substrates was over 95 %.
