Leuconostoc Mesenteroides are epiphytic bacteria that are wide spread in the natural environment and play an important role in several industrial and food fermentations.

Leuconostoc mesenteroides is a facultative anaerobe requiring complex growth factors and amino acids. L. mesenteroides is perhaps the most predominant LAB species found on fruits and vegetables and is responsible for initiating the sauerkraut and other vegetable fermentations. L. mesenteroides starter cultures also used in some dairy and bread dough fermentations.

Commercial production dextrans and levans by L. mesenteroides, for use in the biochemical and pharmaceutical industry, has been carried out for more than 50 years.

Currently, L. mesenteroides has significant roles in both industrial and food fermentations.


  • Dextranase are used in the manufacture of blood plasma extenders, Heparin substitutes for anticoagulant therapy, cosmetics and other products.
  • Another use of Dextranase is the manufacture of Sephadex gels or beads, which are widely used for industrial and laboratory protein seperations.
