The genus of Sutterella was isolated from human and dog feces, Gut microbiota affect human fitness in a variety of ways; one except Sutterella wadsworthensis was isolated from human way is that the production of metabolites by microbes contri- appendiceal and peritoneal fluid.

The whole-genome imbalance of the gut microbiota called dysbiosis may be sequence of the isolate was analyzed by PacBio Sequel associated with diverse diseases, not only metabolic diseases platform. The genome consists a 2,987,884 bp chromosome with a G + C content of 58.30%, 2,436 total genes, 18 rRNA but also mental disorders like autism (Backhed et al., 2012). genes and 63 tRNA genes. In addition, we found that strain Despite the increasing knowledge about gut microbiome due to KGMB03119 had several genes for antibiotic resistance and the development of metagenome analysis technology, it is still bile acid resistance in its genome based on the result of genome difficult to study gut microbiota because of the lack of gut analysis. microbe resources. As the need for collection and storage of gut Keywords: Sutterella sp. KGMB03119, antibiotic resistance, bile microbiota for therapeutic applications increases (Bolan et al., acid resistance, human feces 2016), Korean gut microbiome bank launched in 2016. Recently, a novel bacterial strain designated KGMB03119 was isolated from a Korean fecal sample. Based on phylogenic, phenotypic and chemotaxonomic characteristics, strain KGMB03119 (= KCTC 15823T) was identified to a novel species as a member of *For correspondence.

For example, S. wadsworthensis was resistant to piperacillin, For the whole genome sequencing of strain KGMB03119, which is β-lactam antibiotic of the ureidopenicillin class the genomic DNA was extracted using a Wizard genomic DNA (Molitoris et al., 1997).
