Abstract Sludge treatment with microbe is one of the advanced methods,while it is limited to microbe source. The microbes inside of sludge are a kind of indigenous microorganism suit to deal with sludge. In order to investigate microbe distribution inside of sludge and get predominant bacterium crowd from sludge,the sludge bacteria was isolated and purified by plate separation method.Five strains of bacteria were selected as target strain because of the large amount. The species identification of these strains were accomplished by a set of methods including observation of bacterial strain and clone morphology,gram stain,sporeformative and capsule stain,carbon nutrient sources utilization.These images were contrasted with Bergey′s Manual of Systemaic Bacteriology. The results showed that strain A,B,C were Bacillus,strain D was Micrococcus,and strain E was Azomonas.......
