Bacillus sp. stains 2002 and 2003 were isolated from a forest soil samples collected at Taebaek mountain of Gangwon province, Korea. On the basis of the comprehensive taxonomic data from morphological, physiological and biochemical characteristics, and 16S rDNA sequence analysis, BCNU 2002 and 2003 were identified as B. amyloliquefaciens. The in vitro antimicrobial activities against bacteria such as B. subtilis and M. luteus and pathogenic fungi such as Aspergillus niger, Candida albicans, Epidermophyton floccosum, Saccharomyces cerevisiae, Trichophyton mentagrophytes and Trichophyton rubrum were elucidated. The effect of medium components (i.e. carbon and nitrogen sources) and other culture requirements (i.e. initial pH and temperature) on production of antimicrobial antibiotics by Bacillus sp. 2002 and Bacillus sp. 2003 were also investigated in this study. Maximum production of bioactive metabolites in a synthetic medium was found on the seven day of incubation. Furthermore, maintaning the incubation temperature at 28℃ under shaking condition was found to be optimum for maximum antimicrobial activity. In addition, BCNU 2002 and BCNU 2003 were determined to have the ability to produce enzymes such as amylase, protease, gelatinase and catalase.
