摘　　要：目的分离、培养、鉴定山湖水中能抑制藻类生长的优势菌。方法于2005年8月,采集重庆四面山地区的山湖水水样,通过增菌培养、平板划线分离、菌种鉴定实验获得优势菌,并将优势菌应用于富营养化水体中进行生物-生态修复,观察藻类生长情况,并进行水质检验。结果四面山山湖水中含有弗劳地枸橼酸杆菌、门多萨假单胞杆菌、木糖氧化无色杆菌和维氏气单胞菌共4种优势菌群。实验室藻类生长抑制实验结果显示,空白对照组水样的藻类生长速度较快,实验前富营养水体的色度、浑浊度、COD_(Mn)分别为30度、29.8NTU 和8.7mg/L;含有弗劳地枸橼酸杆菌、门多萨假单胞杆菌实验水样中藻类生长被抑制,COD_(Mn)分别为7.1、7.4mg/L,色度均为20度。结论山湖水中的弗劳地枸橼酸杆菌和门多萨气单胞杆菌的藻类抑制作用较明显。Objective To find the dominant bacteria in mountain-lake water which can inhibit the alga growth by separation, culture, identification. Methods The samples from the lake in Simian Mountain area, Chongqing were collected. Bacteria-increasing culture, separation and identification were conducted to choice the dominant bacteria. With the dominant bacteria, the ecological restoration was conducted in the eutrophicaled water in laboratory, the growth of alga was observed and the water quality was determined. Results Citrobacter freundi, Pseudomnas mendocina, Aerornonas veronii, Achromobacter xylosoxidans were the dominant bacteria in the lake in Simian Mountain area, Chongqing. Compared with the blank water control, the algae growth speed was slower. CODMn, was 7.1 and 7.4 mg/L respectively, the chroma was both 20 degree in the experimental water samples with Citrobacter freundii and Pseudomonas mendocina. Conclusion The algae inhibitory action of Citrobacter freundii and Pseudomonas mendocina in the mountain lake water is obvious.
