Complete genome sequence of Leuconostoc suionicum DSM 20241T provides insights into its functional and metabolic features

Abstract The genome of Leuconostoc suionicum DSM 20241T (=ATCC 9135T = LMG 8159T = NCIMB 6992T) was completely sequenced and its fermentative metabolic pathways were reconstructed to investigate the fermentative properties and metabolites of strain DSM 20241T during fermentation. The genome of L. suionicum DSM 20241T consists of a circular chromosome (2026.8 Kb) and a circular plasmid (21.9 Kb) with 37.58% G + C content, encoding 997 proteins, 12 rRNAs, and 72 tRNAs. Analysis of the metabolic pathways of L. suionicum DSM 20241T revealed that strain DSM 20241T performs heterolactic acid fermentation and can metabolize diverse organic compounds including glucose, fructose, galactose, cellobiose, mannose, sucrose, trehalose, arbutin, salcin, xylose, arabinose and ribose.
