Succession Law of Cultivable Desulfuration Microorganism during Domestication

Article Preview

Abstract:

A desulfuration bacterial community with high efficiency of removing SO2 were obtained with inductive domestication method. The isolated cultures technique and 16S rRNA gene sequencing technique were used to investigate the bacterial community structure and dynamic change in domestication process. The results showed that 13 species were identified from 45 isolated strains from bacterial community after 7d ,14d and 21d domestication, they were the first find associated with removing SO2.The community structure varied significantly in domestication process during which some species kept stable while others were replaced by new species gradually. The results confirmed Rhodococcus erythropolis had good desulfurization ability and stability , might be the key microorganism involved in removing SO2, were preliminarily confirmed dominate species. Other dominant bacteria were Pseudomonas putida and Microbacterium oxydans.Isolated strains and their gene imformation provided a lot of microbial resources for development microbial desulphurization technology of contained SO2 tail gas.
