Heterologous expression of a position 2-substituted (1-->3)-beta-D-glucan in Lactococcus lactis.

ABSTRACT: Exopolysaccharides play an important role in the rheology and texture of fermented foods, and among these beta-glucans have immunomodulating properties. We show that the overproduction of the Pediococcus parvulus GTF glycosyltransferase in an uncapsulated Lactococcus lactis strain results in synthesis and secretion (300 mg liter(-1)) of a position 2-substituted (1-->3)-beta-D-glucan that has potential use as a food additive.
