In this study, an acidoduric Streptomyces strain was isolated and identified from acidic forest soil around Dankook University, Cheonan Campus. This isolated strain had rod-shaped, smooth, non-motile spore and the shape of spore chain was compact spiral. This structure appeared similar to the sporangium of the genus Streptosporangium but this strain proved to be a Streptomyces strain by an electron microscopic study and cell wall analysis. This strain showed a best growth on neutral medium, was also able to grow on the acidic media of pH 4.0 and pH 5.0. The color determination of this strain on various agar media and other physiological tests were carried out by ISP-methods. From these results, the isolated strain was considered to be Streptomyces mirabilis.
