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 Lacticaseibacillus. The multi-locus sequence tree revealed that the strain formed a sub-cluster adjacent to Lacticaseibacillus kribbianus. The main fatty acids were C16ââ0 and C18ââ1ω9c. The average nucleotide identity value, average amino acid identity, and genome-to-genome distance for YH-lacS6T and its most closely related strain, L. kribbianus, were 85.4, 85.2 and 29.2â%, 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 meso-diaminopimelic acid. Thus, YH-lacS6T (=KCTC 21186T=JCM 34954T) represents a novel species. The name Lacticaseibacillus parakribbianus sp. nov. is proposed.
