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 (Staphylococcussp .)、芽孢杆菌属 (Bacillussp .)和节杆菌属 (Arthrobactersp .) ;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 。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.
