Continuous deodorization of malodorous sulfur compounds by Thiobaillus neapolitanusts R-10 immobilized onto a polypropylene pellet was studied using a column reactor at 30C. The maximum amounts of immobilized cells was 5.3 gall polypropylene with 57.5mm in pellet size, and the amounts of immobilized cells in the higher part of the column was as twice as in the lower part. The optimum pH and temperature for removal of dimethyl sulfide were 6.0 and 30C, respectively. When 5-20 /l of hydrogen sulfide and methylmercaptan were employed 98% of removal efficiency were achieved. In contrast, lower concentrations of dimethyl sulfide and dimethyldisulfide should be supplied to meet satisfactory deodorization efficiency. The immobilized cell column was successfully operated for the deodorization of mixture of sulfur compounds over 15 days without significant loss of initial activity achieving high efficiency.
