摘　　要：从藻类消退期的河流中取水样,分别加入斜生栅藻、铜绿微囊藻、小球藻、人工湖泊中的两种混合野生藻及氧化塘中的野生藻,平行培养1周,考察水样中的溶藻细菌对这些藻类的去除效果。结果表明,对上述水样中的叶绿素a的去除率分别为94.69%、95.41%、94.50%、89.19%、92.67%和95.63%。采用PCR-DGGE指纹分析技术初步研究了加入不同藻类水样的微生物群落结构,结果表明加入藻类的水样与原始水样的群落结构存在较大差异,但加入不同藻类的水样之间的相似度较高。溶藻系统中的微生物种类包括未培养的细菌类、Bacillus sp.、Bacillus cere-us、Stenotrophomonas sp.等。The water samples were taken from the river in the decline period of algae. Scenedesmus,Microcystis aeruginosa,Chlorella,two mixed wild algae from artificial lake and wild algae from eco-pond were mixed respectively with the water samples. The removal efficiencies of those algae by the algae-lysing bacteria in the water samples were investigated by parallel culture for a week. The results show that the removal rates of chlorophyll-a are 94.69%,95.41%,94.50%,89.19%,92.67% and 95.63% respectively. The microbi...
