Rastrelliger Kanagurta

The biomedical potential of fish gut-associated actinobacteria isolated from the marine fish Rastrelliger kanagurta (Indian mackerel) was investigated. The actinobacterial strain IM20 was isolated from the fish gut by using Kusters agar medium prepared with 50% sea water. Based on their phenotypic and molecular characteristics, strain IM20 was identified as Streptomyces maritimus. The bioactive metabolites produced from the strain IM20 by agar surface fermentation and ethyl acetate extraction were tested for in vitro antimicrobial, antiquorum sensing , anti-biofilm, anti TB, anti-oxidant and anti-cancer activity. The MIC value of ethyl acetate extract (EAE) of IM20 was found to be 16 μg ml−1 against S. aureus and E. coli. In quorum sensing inhibition assay, the extract showed violacein inhibition upto 87% at 512 μg ml−1 concentration when tested by pigment inhibition assay using C. violaceum MTCC 2656. The results of in vitro assays revealed that the ethyl acetate extract of IM-20 (EAE-IM20) showed 75%, 83% and 72% inhibition against Mycobacterium tuberculosis H37Rv, M. tuberculosis (SHRE sensitive) and multi drug resistant (MDR) M tuberculosis respectively at 500 μg ml−1 concentration. In DPPH assay, 71% radical scavenging activity was exhibited by the EAE-IM20 at 250 μg ml−1. In MTT assay, EAEIM20 exhibited 74.29±2.01% inhibition on breast cancer cell line MCF7 (250 μg ml−1). This study broadly determines that the fish associated actinobacteria is a prolific place for diverse multifunctional bioactive compounds for the development of medically important unique drugs.
