Abstract
In this study we are focused on the color groups of actinomycetes, in particularly
streptomyctes, in soil of western region of KSA. Therefore, we collected soil samples from different
climate locations in KSA (Taif, Makah and Jeddah).The color groups of the isolated actinomycete
isolates were determined. The antagonistic activities of the isolated actinomycetes were also tested
against seven microorganisms including, bacteria and fungi. The highest active isolates were
identified as strains of S. polychromogenes (isolate 08), S. chattanoogensis (isolate 14), S. lucensis
(isolate 20), S. violaceus (isolate 21), S. violans (isolate 32), S. griseorubiginosus (isolate 34), and
S. antibioticus (isolate 35). It was show that the 7 selected streptomycete isolates were able to grow
in the presence of 7% NaCl in the starch nitrate agar medium. At concentration of 10.5% NaCl, four
isolates grew with weak growth (+) and three isolates showed in-doubt growth (±).
