Abstract
Trichoderma spp. are the aggressive causal agents for green mold disease on oyster mushroom (Pleurotus spp.) cultivation. Antifungal bacteria (KATB 99121, KATB 99122 and KATB 99123 strains) were isolated from the compost for Pleurotus ostreatus. Among these bacterial strains, KATB 99121 strain showed an excellent inhibitory activity to the pathogens for green molds such as T. harzianum, T. viride and T. hamatum and an animal pathogen, Candida albicans, but did not affect on the culture of Pleurotus ostreatus (2209, Chunchu 2 and Wonhyung strains). KATB 99121 strain secreted amylolytic, proteolytic and cellulolytic exoenzymes. KATB 99122 and KATB 99123 strains excreted amylolytic, proteolytic, cellulolytic, lipolytic exoenzymes and showed ${\beta}$-glucosidase activity. Further studies will be conducted on the development of microbial fungicides using the antagonistic bacteria for the control of green mold disease on Pleurotus spp.
