从某印染厂的活性污泥中分离到一株能利用邻苯二甲酸二甲酯（DMP）、邻苯二甲酸二乙酯（DEP）和邻苯二甲酸二丁酯（DBP）作为唯一碳源和能源的好氧细菌。根据其形态特征、生理生化特征和16 S rDNA序列分析，将其鉴定为红色红球菌（Rhodococcus ruber）。通过对Rhodococcus sp.L4降解邻苯二甲酸二辛酯、邻苯二甲酸二辛酯和邻苯二甲酸二辛酯的批量试验，确定了该菌降解邻苯二甲酸二辛酯、邻苯二甲酸二辛酯和邻苯二甲酸二辛酯的最适pH值、最适温度和最适底物浓度为：pH7.0 - 8.0，30 -37 ℃和PAEs浓度
In this study, an aerobic bacterial strain capable of utilizing dimethyl phthalate (DMP), diethyl phthalate (DEP) and di-n-butyl phthalate (DBP) as sole carbon source and energy was isolated from activated sludge collected from a dyeing plant. According to its morphology, physiochemical characteristics and 16S rDNA sequence, the strain was identified as Rhodococcus ruber. The biodegradation batch tests of DMP, DEP and DBP by the Rhodococcus sp. L4 showed the optimal pH value, temperature and substrate concentration: pH 7.0-8.0,30-37 degrees C and PAEs concentration
