采用生物滴滤塔能够有效去除含苯乙烯恶臭气体,塔内微生物中含有大量的球菌和杆状菌。采用聚合酶链式反应-变性梯度凝胶电泳(PCR-DGGE)技术研究处理苯乙烯恶臭气体的生物滴滤塔填料表面的微生物,结果表明,去除苯乙烯生物滴滤塔中有5种菌为降解苯乙烯的优势菌种;通过16S rDNA基因扩增测序同源性比对,结果显示嗜甲基杆菌属(methylophilus)丰度为50.5%,2种变形菌属(alpha proteobacterium、delta proteobacterium)相对丰度分别为16.9%和11.6%。
The use of biological trickling filter tower can effectively remove the odor of styrene-containing gases, tower microorganisms contain a large number of cocci and bacilli. Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) was applied to study the microorganisms on the surface of the biotrickling column packed with styrene malodorous gas. The results showed that five kinds of bacteria were removed from the biotrickling column Degradation of dominant strains of styrene; by 16S rDNA gene amplification sequencing homology comparison showed that the genus methylophilus abundance was 50.5%, two kinds of proteobacterium (alpha proteobacterium) relative Abundance of 16.9% and 11.6% respectively.
