The study was conducted at the general company for the manufacture of medicines and medical supplies in Samara and the laboratories of the Department of Life Sciences-Faculty of Education / Samara University for a period from 3/9/2022 to 10/3/2023, where 40 soil samples were collected at depth of 2-7 cm from the soil of the Samara pharmaceutical laboratory to isolate Streptomyces bacteria, then isolated and diagnosed using phenotypic, transplant and biochemical tests that showed that it is a producer of inhibitory factors through its ability to inhibit Staphylococcus aureus bacteria. The results of the test showed the effectiveness of inhibitory agents secreted from Streptomyces bacteria had a certain effect in inhibiting the tested bacteria, as it gave the highest rate of inhibitory diameter of bacterial leaching by 21.7 mm in the direction of Staphylococcus aureus bacteria.
