Isolation of an gelatinase - producing Streptomycete from Egyptian soil and its characterization

ABSTRACT

An actinomycete which produced appreciable quantities of protease was isolated. The mature aerial mass of the organism is in the yellow colour series when grown on the ISP media. Long chains of unbranched sporophores occur in both the aerial and substrate mycelia. The Spore surface is smooth. LL-Diaminopimelic acid could be detected in the whole cell hydrolysate. These characteristics indicated that it was Streptomyces spheroides. Optimum environmental conditions of gelatinase production wore established in cultures at 30§ after 8 days of incubation at pH 7.5
