A novel dextransucrase is produced by Leuconostoc citreum strain B/110-1-2: an isolate used for the industrial production of dextran and dextran derivatives.

The industrial Leuconostoc strain B/110-1-2 producing dextran and dextran derivatives was taxonomically identified by 16S rRNA as L. citreum. Its dextransucrase enzymes were characterized according to their cellular location and reaction specificity.
