非正常排放的酚类物质是对生活环境的有毒污染物。在这项工作中，一个新分离的2，3-二甲基苯酚降解假单胞菌菌株的操作条件，包括温度，溶解氧，和pH值进行了研究。混合酚在稀盐介质中可以有效降解，避免了过量的氨氮和磷酸盐污染。结果表明，在不引起富营养化的情况下，通过添加细菌生长营养物，细菌修复酚类污染物的潜力。
Abnormally discharged phenols work as toxic pollutants to living environments. In this work, the operation conditions of a newly isolated 2,3-dimethylphenol-degrading Pseudomonas strain including temperature, dissolved oxygen, and pH were investigated. Mixed phenols could be degraded efficiently in diluted mineral-salts medium, avoiding excessive ammonia and phosphate pollution. The results illustrated the potential of bacterial remediation of phenolic pollutants without eutrophication caused by the addition of bacterial growth nutrients.
