Abstract

<italic>Corynebacterium </italic>sp. SCR221107 was isolated from the rumen fluid of healthy male Holstein dairy cows from a research farm at Suncheon, Jeollanam-do, Korea. <italic>Corynebacterium </italic>sp. SCR221107 is a functional probiotic candidate that produces vitamin B<sub>12</sub>. All <italic>Corynebacterium </italic>sp. SCR221107 was sequenced using the PacBio RS II and Illumina HiSeq platforms and assembled de novo. The complete genome sequence of <italic>Corynebacterium </italic>sp. SCR221107 contained one circular chromosome (3,043,024 bp) with a guanine + cytosine (GC) content of 60.1%. Annotation analysis showed the presence of 2,639 protein-coding sequences, 15 rRNA genes, and 57 tRNA genes. Genome analysis found that <italic>Corynebacterium </italic>sp. SCR221107 encodes various genes associated with vitamin B<sub>12</sub> synthesis and transport. The genomic information provided a detailed understanding of <italic>Corynebacterium </italic>sp. SCR221107, suggesting that this isolate may have potential probiotic applications.
