JF International Journal of Systematic and Evolutionary Microbiology, VO 62 IS Pt_7 SP 1548 OP 1551 DO https://doi.org/10.1099/ijs.0.031203-0 PB Microbiology Society, SN 1466-5034, AB Strains LMG 8159 and LMG 11499 were reclassified by a polyphasic approach, including 16S rRNA gene sequence analysis, 16S–23S rRNA intergenic spacer (IGS) sequence analysis, (GTG)5-PCR fingerprinting, RAPD fingerprinting, fatty acid methyl ester analysis and an analysis of phenotypic features using API 50 CH. The two strains were closely related to the type strains of the three defined subspecies of Leuconostoc mesenteroides , showing 99.7–99.9 % 16S rRNA gene sequence similarity, 99.2 % 16S–23S rRNA gene intergenic spacer sequence similarity, 97.1–97.4 % pheS gene sequence similarity and 98.0–98.2 % rpoA gene sequence similarity. Low atpA gene sequence similarity (91.4–91.7 %), (GTG)5-PCR fingerprinting, RAPD fingerprinting, fatty acid compositions and phenotypic features allowed us to differentiate strains LMG 8159 and LMG 11499 from all established subspecies within L. mesenteroides . Based upon the data obtained in the present and previous studies, a novel subspecies is proposed within the species L. mesenteroides , Leuconostoc mesenteroides subsp. suionicum subsp. nov., with the type strain LMG 8159T ( = ATCC 9135T  = DSM 20241T  = NCIMB 6992T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.031203-0
