Plantaricin is a bacteriocin produced by Lactobacillus plantarum. It has potential as probiotic, antimicrobial, easily degraded by proteolytic enzyme and Generally Recognized as Safe (GRAS). The objective of this study was to produce plantaricin F expressed from Lactococcus lactis pNZ8148-plnAF, purified using gel-filtration chromatography and investigated its antimicrobial activity using disc diffusion method against Candida albicans using nystatin as a positive control. Crude plantaricin F yield was 1.23 grams. Gel-filtration chromatography using Sephadex G-50 of plantaricin F yielding in 25 fractions. 5 fractions (fraction no 7, 9, 17, 18, 19) from 25 fractions have antimicrobial activities based on the clear zone on disc diffusion method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
