| 摘 要： | 从武汉市的池塘分离到3株编号分别为M6，M8和M13的溶藻细菌，对这3株细菌的生理生化特性、溶藻专一性和溶藻原因进行了研究。结果表明：M6，M8和M13分别属于葡萄球菌属（Staphylococcus sp.）、芽孢杆菌属（Bacillus sp.）和节杆菌属（Arthrobacter sp.）；它们分别能溶解鲍氏织线藻、念珠藻、鱼腥藻、坑形席藻、铜绿微囊藻、鞘丝藻等多种蓝藻，并且它们的液体溶藻现象较固体溶藻现象明显；3株溶藻细菌培养液的过滤液仍有溶藻效应，说明溶藻原因可能是细菌释放某种化学物质所致。

| Abstract: | Three bacteria strains,M6,M8 and M13,isolated from ponds in Wuhan City,showed algae-lysing effects on blue-green algae (cyanobacteria).Their physiological and biochemical properties,algae-lysing specificity and lytic phenomena were investigated.The results showed that M6,M8 and M13 were characterized to be Staphylococcus,Bacillus and Arthrobacter respectively.Three bacteria present a broad algae-lysing range,i.e.they lysed Plectonema boryanum IU594,Nostoc sp.96,Anabaena sp.PCC595,Phormidium foveolarum IU427,Miorocystis aeruginosa, Lyngbya ketzingii IU1547 tested.Likewise,the infecting effects of the bacteria on the blue-green algae were more markedly in liquid medium than in solid medium.It was observed that the filtrates of the bacterial culture showed significant lytic effect on blue-green algae,indicating that the anti-algae effect results from the substances released by the bacteria. |
