Draft genomes and antibiotic resistance profiles of four Enterococcus faecium strains isolated from Cheonggukjang, Korean fermented soybean paste = 청국장에서 분리한 4가지의 Enterococcus faecium 균주의 유전체 및 항생제 내성 유전 분석

Abstract

Enterococcus faecium is a facultative anaerobic, Gram-positive bacterium found in the gut and fermented foods, with some strains exhibiting probiotic potential by modulating the microbiota and producing beneficial metabolites. This study analyzed the genomic sequences of four E. faecium strains isolated from Cheonggukjang. The genome sizes of JB00005, JB00012, JB00023, and JB00034 were 2,612,572 bp (GC content: 38.47%), 3,034,373 bp (GC content: 38.36%), 2,960,038 bp (GC content: 38.30%), and 2,736,348 bp (GC content: 38.23%), respectively. Four antibiotic resistance genes and a Bac32-related bacteriocin gene were identified. The PBP5 amino acid sequence exhibited both the sensitive (S) genotype and a combined (S/R) genotype.
