Isolation, characterisation and antimicrobial activities of marine topse ( <i>Polynemus paradiseus</i> ) fish oil: an overview

In the past few decades, there has been a growing interest in fish oils because of their significant health benefits. Marine <i>Polynemus paradiseus</i> fish locally named as topse fish are indigenous source which thrives in West Bengal's marine areas, India. Furthermore, there is a limitation of current study on <i>P. paradiseus</i> FO. The present study aimed to investigate <i>P. paradiseus</i> FO's chemical index and antibacterial effectiveness against the pathogenic microorganisms. The quality indexes of oil were conformed to Codex Alimentarius Standard. The broth microdilution method was used to assess the antibacterial properties of <i>P. paradiseus</i> FO and its interaction with antibiotics. Inhibition zones and MIC value of <i>P. paradiseus</i> FO against bacterial strains ranged from 13 to 18 mm and from 15 to 55 μg/mL, respectively. Our findings indicated <i>P. paradiseus</i> FO may be regarded as a viable antibacterial agent for enhancing food safety through the management of foodborne infections.
