Ochrobactrum anthropi is a gram-negative bacillus recognized as a human opportunist pathogen isolated in clinical specimens and not of clinical significance. We report a new aspect of this bacterium, that it has been isolated from activated sludge. In fact, it is able to grow on atrazine (2-chloro-4-ethylamino-6-isopropyl-amine-s-triazine) by utilizing it as the only source of carbon. Our results show that atrazine (0.03 g/liter) causes a dramatical increase in the degree of saturation of membrane fatty acids. Analysis and identification of bacterial fatty acids were performed by gas chromatography and gas chromatography-mass spectrometry techniques.
嗜麦芽窄食单胞菌是一种革兰氏阴性杆菌，被认为是一种在临床标本中分离出的人类机会致病菌，且无临床意义。我们报道了这种细菌的一个新情况，即它已从活性污泥中分离出来。事实上，它能够以莠去津（2-氯-4-乙氨基-6-异丙氨基-s-三嗪）为唯一碳源生长。我们的结果表明，莠去津（0.03克/升）会导致膜脂肪酸饱和度显著增加。通过气相色谱和气相色谱-质谱技术对细菌脂肪酸进行了分析和鉴定。
