Investigating the antioxidant potential of Streptomyces sp. MUSC 11 from mangrove soil in Malaysia

Abstract

Streptomyces are a distinguished group of gram-positive bacteria mostly acknowledged for their immense contribution to life-saving drugs and lines of compounds with diverse bioactivities. To date, there remains limited studies on Streptomyces with biological activities residing in underexplored ecosystems such as the mangrove forests. For this purpose, the present work aimed at investigating the biological activity of Streptomyces sp. MUSC 11 collected from soil sample in mangrove forests, situated in the State of Pahang, Peninsular of Malaysia. The cultured strain resembled phenotypic and genotypic traits of genus Streptomyces. Investigations of the methanolic extract from Streptomyces sp. MUSC 11 revealed antioxidant activities in form of scavenging free radicals ABTS, DPPH, chelating iron and reducing ferric iron. Besides the antioxidant tests, antioxidant results corresponded well to the presence of phenolic content. In summary, Streptomyces derived from extreme and understudied ecosystem such as the mangrove forests are potential sources of biologically active and therapeutically useful compounds.
