Date Aug. 10, 1989.A method for the production of oligodextrans containing an alpha (1-2) bond which uses glycosyltransferase from Leuconostoc mesenteroides, particularly strain B-1299, sucrose and an accepter moiety such as glucose, maltose, isomaltose, isomaltotriose or methyl alpha -glucose. Optionally, this product may be further treated with an endodextranase or glucosamylase.
