The objective of this research was to known antibacterial activity of 4 endhophytic Streptomyces namely Streptomyces griseorubiginosus,   Streptomyces vellosus, Streptomyces diastaticus and Streptomyces griseoruber against Staphylococcus aureus and Eschericia coli and measure the biggest antibacterial activity which is indicate by clear zone diameter. Antibacterial activity by using agar plug diffusion method showed that Streptomyces vellosus has capable to inhibits growth of Staphylococcus aureus but not with Eschericia coli and Streptomyces diastaticus has capable to inhibits growth of Eschericia coli but not with Staphylococcus aureus. The clear zone of  Streptomyces vellosus and          Streptomyces diastaticus are 5,18 mm and 7 mm respectively.                Streptomyces griseoruber and Streptomyces griseorubiginosus can’t grow during isolation.  Keyword: Streptomyces vellosus, Streptomyces diastaticus, agar plug diffusion method

Streptomyces Griseoruber

The taxonomic position of a novel actinomycete isolate, designated strain GGCR-6T, isolated from the healthy leaves of Xanthium sibiricum collected from the botanic garden of Hunan University of Science and Technology in Hunan province, PR China, was determined by a polyphasic approach. GGCR-6T grew well on ISP series media and formed well-developed, branched substrate hyphae and aerial mycelium that differentiated into straight spore chains consisting of cylindrical spores with smooth surfaces. The diagnostic diamino acid was ll-diaminopimelic acid. The major menaquinones were MK-9(H8), MK-9(H2), MK-9 and MK-9(H6). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphotidylinositol and phosphatidylinositol mannosides. The predominant fatty acids were C16 : 1ω9c, iso-C16 : 0 and C16 : 0. The phenotypic characteristics of GGCR-6T indicated that it represented a member of the genus Streptomyces . Phylogenetic analysis based on the 16S rRNA gene sequence indicated that GGCR-6T was most closely related to Streptomyces cyaneus NRRL B2296T and Streptomyces griseoruber NRRL B1818T. However, the digital DNA–DNA hybridization, the average nucleotide identity and the multi locus sequence analysis evolutionary distance clearly separate GGCR-6T from the phylogenetically closely related species. Furthermore, the novel isolate was distinctly differentiated from S. cyaneus NRRL B2296T and S. griseoruber NRRL B1818T by morphological, physiological and biochemical characteristics. Based on these data, strain GGCR-6T should be designated as a representative of a novel species of the genus Streptomyces , for which the name Streptomyces aquilus sp. nov. is proposed. The type strain is strain GGCR-6T (=CICC 11055T=JCM 33584T).
