| Abstract: | Biofilter is one of the bio-technologies for waste gas treatment. Bacteria and fungi are the two dominant microorganism groups in biofilters. The degrading ability to hydrophobic organic compound and adaptability to acid and dry conditions of fungi are higher than those of bacteria. In this experimental research, a biofilter was used to treat a waste gas with ethyl mercaptan (EM). The microorganisms attached to the media in the biofilter were isolated and identified. The results showed that identified microorganisms are Penicillium frequentans, Paecilomyces variotii, Aspergillus wentii and Cephalosporium acremonium. |
