five strains of Streptomyces spp. with high Productivity of glucose isomerase (15-30 units/ml) were obtained among 280 microbial strains isolated from 150 soil samples. These strains produced glucose isomerase with xylose as an inducer. These 5 strains were also identified to be different strains of Streptomyces spp.：streptomyces sp. K-14, K-53, K-71, K-77 and K-733. It was found that Streptomyces sp. K-14 produced the highest enzyme activity. The spore chains of these strains were rectiflexible and spore surface was smooth except Steptomyces sp. K-77 and K-733, with spiny surface.
