Abstract

Nontuberculous mycobacteria (NTM) are environmental microorganisms, also known as opportunistic pathogens, found in patients with pulmonary tuberculosis. The emergence of antibiotic resistance is increased by prolonged antibiotic treatment for NTM infections. Therefore, alternative sources of new antibiotics are essential for the treatment of NTM infections. A marine actinobacterium, Streptomyces sp. BTA 1-131, isolated from a marine sponge, Melophlus sarasinorum, has been reported as a potential source of antibacterials and anticancer agents. The present study aimed to investigate the potential of Streptomyces sp. BTA 1-131 against two NTMs: Mycobacterium smegmatis and Mycobacterium fortuitum. Streptomyces sp. BTA 1-131 was fermented in three cultivation media (SYP, ISP2, and YS), and the secondary metabolites were extracted using methanol. The bioactivity screening showed inhibition of all methanolic extracts against the growth of M. smegmatis and M. fortuitum. The methanolic extract, which could inhibit both mycobacteria, was a crude extract derived from SYP liquid medium fermentation. The isolated compounds in this study were preliminarily identified using thin-layer chromatography (TLC). The TLC results showed different potential compounds in the crude extracts of Streptomyces sp. BTA 1-131 also highlighted the impact of the fermentation medium on the production of metabolites from Streptomyces. This study also added knowledge about the importance of the Indonesian marine actinobacterium Streptomyces sp. BTA 1-131 as a promising producer of anti-NTM compounds.

Abstract

Sponges are sources of various useful natural products. The natural compounds derived from sponges are mostly complex polyketide. The polyketide synthase genes (PKS) is responsible for the biosynthesis of complex polyketides. During this research, we detected ketosynthase (KS) gene domain from 10 species of marine sponges, collected from Mediterranean Sea (Aplysina aerophoba, Petrocia ficiformis, Axinella damicornis, Axinella veronicas, Crambe crambe) and North Sea (Halichondria panicea, Haliclona xena, Haliclona oculata, Suberites massa, Ephydatia fluviatilis). We also detected KS gene domain from 12 bacterial sponge isolated from H. panicea. We used a PCR-based approach to detect the ketosynthase (KS) gene domain of Polyketosynthase (PKS) genes. Our result showed that the sponges and the bacterial sponges are mostly KS positive (700 bp). The presence of the PKS gene indicates the ability of the sponges to produce bioactive compound and potential natural product. The presence of the KS domain in both of the sponges and the bacterial sponges might also indicate that the bacterial sponges involved in the biosyntesis of secondary metabolite of the sponges.
