| 摘 要： | 从焦化厂污水处理曝气池泥样中分离出具有降解苯酚能力的UW7菌株,根据形态、生理生化性状初步鉴定为不动杆菌属(Acinetobacter).该菌16S rRNA基因序列(在GenBank中的登录号为GU083586)与多株鲁氏不动杆菌(A.lowffii)的相似性在99%以上.结合形态、生理生化特性,鉴定UW7菌株为鲁氏不动杆菌(A.lowffii UW7),该种细菌具有降解苯酚的特性尚未见报道.该菌株降解苯酚的最适温度为30℃,最适生长pH 7.0,对2.5 g/L浓度的苯酚能够有效降解,对3.5～4.0 g/L浓度的苯酚有较强的耐受能力,是处理高浓度苯酚废水的良好菌种资源.

| Abstract: | A bacterial strain capable of degrading phenol,designated UW7,was isolated from activated sludge of a wastewater treatment plant in a coking chemical factory.Strain UW7 was identified as Acinetobacter lowffii according to its morphological,physiological and biochemical properties,and the analysis of its 16S rRNA gene sequence that showed more than 99% similarity to several strains of A.lowffii.A strain of A.lwoffii able to degrade phenol had never been reported.The optimum pH and temperature for its growth ... |
