Abstract
Five microbial strains that removed hydrogen sulfide (H2S) or methylme rcaptan (CH,SH) gas were newly isolated from soil samples. Strain DO-1 , one of the isolates, was identified as a member of Pseudomonas sp., and it's immobilized cells removed 1 or 10 ppm of H2S gas within 2 hou rs. When strain DO-1 was cultured aerobically in a flask containing nu trient broth medium, the deodorizing activity increased, depending on the growth of the culture, and the maximum activity was obtained after 48 hours. Even though the immobilized cells were stored at 4 or 25 de grees C in sealed bottles for 6 months, the deodorizing activity remai ned. Throughout this study, strain DO-1 removed H2S gas without prelim inary feeding or exposure to sulfur compounds as growth substrates or inducers. These characteristics are advantageous for the deodorization of the malodorous gases surrounding us in daily life.
