In this study, a symbiotic microbial consortium, which consists of Lactobacillus spp., Actinomycetes, Rhodopseudomonas spp:, Saccharomyces spp.; and Chrysophyta, was applied for treatment of odorous volatile organic compounds (VOCs) and hydrogen sulphide (H2S) from waste gas streams. The microbial consortium was seeded in a lab-scale bio-trickling reactor that packed with coal slag and fire expanded clay pellet. The results showed that this system was effective in treating a mixture of odorous contaminants (VOCs and H2S) simultaneously. High removal efficiencies were attained for both VOCs (>99%) and H2S (>98.5%). The bioreactor also showed long term stability, no clogging or aging problems of the packing medium were encountered, indicating a good potential for industrial scale up. Copyright © 2007 Acta Press.
