This study was conducted to separate microorganisms with excellent odor component decomposition ability from nature. Microorganisms growing sulfur and ammonia compounds as substrates were isolated and identified in the tidal flat of Suncheon Bay. The strain YUN4 cultured on ammonia and sulfur compound substrates was found to have 100% genetic homology to Streptomyces fulvissimus. The optimum growth temperature of YUN4 was 20oC to 40oC, and the optimum pH was investigated in the range of pH 5 to pH 9. In addition, in order to evaluate the ability to reduce odor, after mixing the culture strain with each concentration of 1%, 5%, and 10% in the malodor generating sample, the efficiency of malodor reduction was evaluated after 30 minutes. As a result, the ammonia decomposition efficiency was 82.4%~93.9%, and hydrogen sulfide was 88.7%~94.9%.
