Complete genome sequence of Leuconostoc garlicum KCCM 43211 producing exopolysaccharide

•We present the complete genome sequence of Leuconostoc garlicum KCCM 43211.•This genome comprises a 1,663,492-bp chromosome and two plasmids.•We identified nine genes involved in exopolysaccharide production.•L. garlicum KCCM 43211 can produce exopolysaccharide during sucrose fermentation.•This exopolysaccharide may have use in commercial prebiotics, food additives, and medical purposes. Leuconostoc garlicum KCCM 43211 isolated from traditional Korean fermented food is an intensive producer of exopolysaccharide (EPS). Here we report the first complete genome sequence of L. garlicum KCCM 43211. The genome sequence displayed that this strain contains genes involved in production of EPS possibly composed of glucose monomers. An uncharacterized EPS from the L. garlicum KCCM 43211 strains was also produced during fermentation in the sucrose medium. The MALDI-TOF results displayed the typical mass spectrometry pattern of dextran. This uncharacterized EPS may have use in commercial prebiotics, food additives, and medical purposes. The complete genome sequence of L. garlicum KCCM 43211 will provide valuable information for strain engineering based on the genetic information.
