Abstract A soil isolate, CM 001 producing antifungal substance, was identified by morphological physiological, and chemotaconomic methods. The strain formed aerial and substrate nycelia on various media. It contained L-diaminopimelic acid and glycin in its cell wall without any characteristic sugar. Saturated branched-chain fatty acids of iso-/anteiso types were shown as major cellular fatty acids. From a number of morphological, physiological, and chemotaxonomic characteristics, the isolate was identified as genus Streptomyces(similarity index 0.445 with Streptomyces californicus). The antifungal activity of the culture supernatant of the isolate was detected against Candida albicans and Saccharomyces cerevisiae. The antifungal substance was water soluble, thermostable, and active in wide range of pH.
