Abstract從紅樹林底泥中馴化富集培養分離得到的苯二甲酸酯類化合物的降解菌。對此菌株進行了16S rDNA分子生物學的鑒定,并研究了該菌對鄰苯二甲酸二甲酯的生物降解特性以及生物降解途徑。實驗得出該菌能夠在鄰苯二甲酸甲酯作為唯一碳源和能源的培養基中生長。鄰苯二甲酸二甲酯能夠在好氧條件下被快速降解,濃度為50 mg/L的鄰苯二甲酸二甲酯在5d內可以完全被降解。用高效液相色譜檢測降解過程,主要的中間產物為鄰苯二甲酸一甲酯(MMP)和鄰苯二甲酸(PA)。試驗結果表明,鄰苯二甲酸二甲酯能夠被紅樹林環境中的微生物降解,而且分離得到的菌株Rhodococcus rubber1k對鄰苯二甲酸二甲酯具有高效的降解作用。 The microbial degradative characteristics of dimethyl phthalate ester (DMP) by a degrading bacterium isolated from mangrove soil were investigated. The bacterial identified as Rhodococcus rubber with 16SrDNA. Experimental results showed that as the sole source of carbon and energy, DMP can be degraded and the degradation intermediates was identified as mono - methyl phthalate (MMP) and phthalic acid (PA). The tentative pathway proposed for degradation of DMP by the bacterium under aerobic condition is very effective. Key words: dimethyl phthalate; aerobic degradation; mangrove; environment endocrine- disrupting
