Microorganism analysis in biotrickling filter for treatment of waste gas containing styrene by PCR-DGGE
PCR-DGGE技术用于处理苯乙烯废气的生物滴滤塔中微生物优势菌种解析

Styrene removal could be achieved with high efficiency in the biotrickling filter packed with ceramsite.There are a large number of coccus and rod bacterial in the biotrickling filter.The microbial community structures in the biotrickling filter for styrene removal were assessed by polymerase chain reaction-denaturing gradient gel electrophoresis(PCR-DGGE).Based on 16S rDNA sequence data,results show that the predominant bacterias for degradation of styrene are methylophilus,alpha proteobacterium,delta proteobacterium,two uncultured bacteriums.The dominant bacteria,methylophilus,takes up 50.5%;while alpha proteobacterium and delta proteobacterium are take up 16.9% and 11.6%,respectively.
