Abstract : Abstract Objective: Searching of high protease producer streptomycetal isolate from West Area of Saudi Arabia. Materials and Methods: A total of 472 Streptomyces isolates were isolates from 118 soil samples that were collected from different localities in West Area of Saudi Arabia. The proteolytic productivities of the collected streptomycetal isolates were determined by gelatin clearance zone technique (GCZ). Results: Twenty five isolates were considered as high protease producers (GCZ of ≥15- ≤ 19 mm), 153 isolates with intermediate protease productivity (GCZ of 15-< 19 mm), and 294 isolates have low enzyme productivity (GCZ of ≥ < 15 mm). The protease productivity of the high protease producing isolates was determined quantitatively. Streptomyces isolate coded S372 had the highest protease productivity which was equivalent to 158.2 ± 8.9 U/ml protease enzymes. The morphological and physiological properties of the selected Streptomyces isolate (S372) were studied. According to the obtained results, the selected organism (Streptomyces S372) was taxonomically classified as Streptomyces gram inofaciens. Conclusion: A high protease producing streptomyces isolate, identified as Streptomyces graminofaciens, was isolated from West Area of Saudi Arabia.
