چکیده:

(Streptomyces olivaceus) was isolated from soils of south- east regions of Iran. It was biologically active against root phytopathogens. The gene coding for biologically active metabolite is valuable in genetic engineering studies in evolvement of transgenic crops having elevated tolerance against phytopathogens. Direct and microscopic observations revealed the morphological criteria as: color of arial mycelium was gray and without melanoid or soluble pigments, reverse color was positive and spore chains were spiral with smooth spore surface. Physiological characterizations indicated that it can utilize Arabinose, Inositol, Mannitol, Fructose, Rhamnose and Sucrose but not Raffinose. Utilization of Xylose was not clear and could not be well postulated.
