【Abstract】 The principal purpose of this work is to explore the composition and activeness of microbial population ZE-1 which is able to decolour dyeing wastewater of silk goods more effectively. Ten strains of bacteria were isolated from the samples collected from experimental dyeing waste water and ten strains from pilot plant dyeing waste water of silk goods. The results showed that the composition of microbial population ZE-1 consisted of genera of Bacillus, Acinetobacier, Achromobacter and Pseudomonas essentially. In microbia population ZE-1 conserved in the lab, the dominant bacteria were Bacillus and Acineto-bocter, which occupied 80% of total number of the isola-ies. The more effective species on strains decolouring dye in microbial population ZE-1 were Bacillus subtilis andAcinctobacter calcoacelicus. Aeromonas punctate and Pseu-domonas No. 19 isolated from pilot-plant samples were effective too.更多还原
