인삼 뿌리썩음 병균, Fusarium solani에 길항적인 Streptomyces species의 동정

Identification of Streptomyces species antagonistic to Fusarium solani causing Ginseng root rot

Among 131 isolates of Strptomyces obtained from ginseng cultivating soil, the two isolates ST59 and ST129 showing high antagonistic activity to Fusarium solani(Mart.) Appel & We. causing ginseng root rot were identified. The two isolates were identified Streptomyces alboniger Porter, et al. and Strptomyces reseolilacinus Pridham, et al., respectively, based on mrophology, cultural, and physiological characteristics on various culture media. Spore chains of ST59 and ST129 were flexuous(RF) and coiled(S). Spore surfaces of two isolates were all smooth. Aerial mass color of ST59 was white series and ST129 red series.
