Five species of filamentous cyanobacteria and two species of Flexibacter were isolated from domestic sewage. Cells and filtrates of F. flexilis and F. sancti lysed the cyanobacterium Oscillatoria williamsii. Inhibition of the photosynthetic electron transport reactions, and glycolate dehydrogenase and nitrogenase activity of O. williamsii due to its incubation with F. flexilis, were observed. Scanning electron micrographs revealed the attachment of F. flexilis to the sheaths of O. williamsii which resulted in the excretion of lysozyme and lysis of the cyanobacterium. Seasonal variations of Flexibacter spp showed that they were more abundant in the aeration tanks during June compared with sewage effluents.
从生活污水中分离出了五种丝状蓝细菌和两种屈挠杆菌属细菌。屈挠杆菌属的柔韧屈挠杆菌和圣洁屈挠杆菌的细胞及滤液可裂解蓝细菌威廉氏颤藻。观察到威廉氏颤藻与柔韧屈挠杆菌共培养后，其光合电子传递反应、乙醇酸脱氢酶和固氮酶活性受到抑制。扫描电子显微镜图像显示柔韧屈挠杆菌附着在威廉氏颤藻的鞘上，这导致溶菌酶的分泌和蓝细菌的裂解。屈挠杆菌属细菌的季节变化表明，与污水排放相比，6月曝气池中的此类细菌更为丰富。
