A bacterial strain Pseudomonas sp.a3 capable of degrading nitrobenzene, phenol and aniline was isolated and characterized. The appearance of aniline as one of the metabolites during the aerobic degradation of nitrobenzene indicated that a novel initial reaction existed in strain a3. To improve the degrading efficiency of strain a3, it was immobilized in the mixed carrier of polyvinyl alcohol and sodium alginate. The optimal concentration of polyvinyl alcohol and sodium alginate in the mixed carrier was 9% and 3% respectively, and the immobilized cells showed stable degradation activity and good mechanical properties. The immobilized cells also exhibited higher tolerances toward acid, high salinity environments than those of free cells. Biodegradation of nitrobenzene mixed with aniline and phenol by free and immobilized cells of Pseudomonas sp.a3 was investigated in comparison. The immobilized cells could completely degrade 300mg/L nitrobenzene within 10 hours in presence of 150 mg/L aniline and 150 mg/L phenol, which revealed that the immobilized cells of Pseudomonas sp.a3 would be a potential candidate for treating nitrobenzene wastewater mixed with other aromatics.
