Screening for Anti Mycobacterium tuberculosis Activity of Streptomyces sp. from Lapindo Mud in Sidoarjo, Indonesia

BACKGROUND: Streptomyces sp. from Indonesian soil have not been explored and isolated to find new strains as a source of antibiotics for the treatment of tuberculosis (TB) disease. AIM: In this study, the effect of Streptomyces spp. from Lapindo mud in Sidoarjo, Indonesia be observed, to find out whether Streptomyces spp. has anti-TB activity. METHODS: The primers Strep F; 5-AGAGTTTGAT CCTGKGTCAG-3 and Strep R; 5-AAGGGAG GTGATCCAKKGKGA-3 were used in polymerase chain reaction amplification of the 16S rRNA gene against Streptomyces strains. The anti-TB activity of Streptomyces sp. was determined by broth dilution method using Middlebrook 7H9 media. RESULTS: The results showed that new types of Streptomyces spp., namely, Streptomyces A, Streptomyces D, Streptomyces Ea, Streptomyces Ep, Streptomyces I, Streptomyces F, and Streptomyces G from garbage dump soils. This result also showed that the activity of Streptomyces I, Streptomyces F, and Streptomyces G could inhibit the Mycobacterium TB growth by with inhibitory zones, respectively, 2 ± 0.3; 8 ± 0.7 and 15 ± 0.9mm, while Streptomyces A, Streptomyces D, Streptomyces Ea, and Streptomyces Ep did not inhibit M. TB. CONCLUSION: Thus, from the results obtained, it can be concluded that Streptomyces extract mainly Streptomyces G has promising anti-TB activity by preliminary in vitro techniques. Therefore, it has the definite potential as a source of compounds that may be developed further into antimycobacterial drugs.
