Abstract

A lactic acid bacterium isolated from pig faeces was characterized using a polyphasic approach. The strain was Gram-stain-positive, rod-shaped, and facultative anaerobic. Phylogenetic analysis of the 16S rRNA gene sequence indicated that the isolate belonged to the genus . The multi-locus sequence tree revealed that the strain formed a sub-cluster adjacent to . The main fatty acids were C and Cω9. The average nucleotide identity value, average amino acid identity, and genome-to-genome distance for YH-lacS6 and its most closely related strain, , were 85.4, 85.2 and 29.2 %, respectively. The G+C content of the genomic DNA was 61.6 mol%. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, aminophospholipids and phospholipids. The cell-wall peptidoglycan did not contain -diaminopimelic acid. Thus, YH-lacS6 (=KCTC 21186=JCM 34954) represents a novel species. The name sp. nov. is proposed.
