摘要: 从3种不同土壤中分离和纯化得到10个石油降解细菌菌株。分离菌株均为好氧菌、革兰氏阴性菌、不形成芽孢的杆菌。10个菌株均能利用中等链长的烷烃、柴油和原油作为碳源,而不能以单环芳烃和多环芳烃为碳源。根据其生理生化性状和16S rDNA序列分析结果表明,分离菌株EVA5,EVA6,EVA7,EVA8和EVA9为假单胞菌(Pseudomonas spp. ), EVA10、EVA11、EVA12、EVA13和EVA14为不动杆菌 (Acinetobacter spp.), 均属于Proteobacteria 的γ 亚群。

AbstractTen strains of crude oil degrading bacteria were isolated from three soil samples. The isolates were Gram-negative, aerobic, non-spore-forming rods. All of the ten isolates were able to grow on nalkanes with medium length, diesel fuel and crude oil, but not polycyclic aromatic hydrocarbon. Based on phenotypic characteristics and 16S rDNA sequence analysis, ten isolates were identified as Pseudomona spp. (strain EVA5,EVA6,EVA7,EVA8,EVA9) and Acinetobacter spp. (strain EVA10, EVA11,EVA12,EVA13, EVA14), respectively.
