Complete genome sequence of Enterococcus faecium strain AJ_C_05 with potential characteristics to break down carbohydrates, applicable to livestock industry

<italic>Enterococcus faecium</italic> (<italic>E.</italic> <italic>faecium</italic>) strain AJ_C_05 was isolated from a Doenjang<italic>, </italic>a traditional Korean fermented food made from soybeans<italic>,</italic> and its complete genome was sequenced using the Oxford MinION platform. The complete genome of <italic>E.</italic> <italic>faecium</italic> strain AJ_C_05 has one circular chromosome and two plasmids. The chromosome of <italic>E.</italic> <italic>faecium</italic> strain AJ_C_05 consists of 2,623,546 base pairs (bp) with a guanine + cytosine (G+C) content of 38.3%, 2,680 coding sequences, 69 tRNAs, and 18 rRNAs. One plasmid is 164,853 bp long and has a G+C content of 35.5%, and the other plasmid is 11,235 bp long with G+C content of 33.1%. <italic>E. faecium</italic> strain AJ_C_05 possesses genes for enzyme determinants, such as alpha-galactosidase (EC 3.2.1.22), beta-glucosidase (EC 3.2.1.21), cellulases (EC 3.2.1.4), chitinase (EC 3.2.1.122), proteases (EC 3.4.21.112), and xylanase (EC 3.2.1.8). These characteristics of <italic>E. faecium</italic> strain AJ_C_05 appears to indicate its potential to be used as probiotic feed additives. This study offers valuable insight into the functionality of <italic>E. faecium</italic> isolated from soybean paste, which has the potential to promote digestion when used as a feed additive.
