Abstract

Lactic acid bacteria (LAB) have been reported to possess various beneficial properties and are commonly used as probiotics. LAB play a crucial role in milk fermentation, industrial lactic acid fermentation, and health and medicine. Limosilactobacillus fermentum isolated from fermented dairy and food products is considered as 'Generally Recognized as Safe' by FDA. Limosilactobacillus fermentum plays an important role in modulation of the intestinal microbiota, enhancing the host immune system and improving feed digestibility. We isolated a probiotic candidate that was identified and named Limosilactobacillus fermentum JNU532. In a previous report, cell-free culture of L. fermentum JNU532 exhibited anti-melanogenic and antioxidant activities. In this study, we present the complete genome assembly of the bacterial strain JNU532. The final genome consists of one circular chromosome (2,077,416 base pairs) with a guanine + cytosine (GC) ratio of 51.5%.
