ABSTRACT
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 eutrophicated water in laboratory,the growth of alga was observed and the water quality was determined.Results Citrobacter freundi,Pseudomonas mendocina,Aeromonas veronii,Achromobaeter xylosoxidans were the dominant bacteria in the lake in Simian Mountain area,Chongqing.Compared with the blank water eontrol,the algae growth speed was slower,COD_(Mn)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.
