sucrose + gentiobiose	gentiobiose is better as an acceptor than isomaltose, acceptor products from gentiobiose, form in good yields (nearly 90% in unoptimized reactions). The initial product is a single trisaccharide, alpha-D-Glcp-(1-6)-beta-D-Glcp-(1-6)-D-Glc. Two tetrasaccharides are formed in approximately equal quantities: alpha-D-Glcp-(1-3)-alpha-D-Glcp-(1-6)-beta-D-Glcp-(1-6)-D-Glc and alpha-D-Glcp-(1-6)-alpha-D-Glcp-(1-6)-beta-D-Glcp-(1-6)-D-Glc. One pentasaccharide is isolated from the reaction mixture, alpha-D-Glcp-(1-6)-alpha-D-Glcp-(1-3)-alpha-D-Glcp-(1-6)-beta-D-Glcp-(1-6)-D-Glc	Leuconostoc mesenteroides	?	-	?
