Abstract

Oligosaccharides formed by a transgalactosylation reaction during lactose hydrolysis with Bifidobacterium bifidum were separated into eight fractions by gel-permeation chromatography and their structures studies determined by trimethylsilylation analysis, methylation analysis, f.a.b.-m.s., g.l.c.-m.s. and enzymic hydrolysis as beta-D-Galp-(1----3)-D-Glc, beta-D-Galp-(1----6)-D-Glc, beta-D-Galp-(1----6)-D-Gal, beta-D-Galp-(1----3)-beta-D-Galp-(1----4)-D-Glc, beta-D-Galp-(1----6)[beta-D-Galp-(1----4)]-D-Glc, beta-D-Galp-(1----2)[beta-D-Galp-(1----6)]-D-Glc, beta-D-Galp-(1----3)-beta-D-Galp-(1----3)-beta-D-Galp-(1----4)-D-Glc, beta-D-Galp-(1----3)-beta-D-Galp-(1----3)-beta-D-Galp-(1----3)-beta-D-Ga lp- (1----4)-D-Glc, beta-D-Galp-(1----3)-beta-D-Galp-(1----3)-beta-DGalp-(1----3)-beta -D-Galp-(1----3)-beta-D-Galp-(1----4)-D-Glc, and beta-D-Galp-(1----3)-beta-D-Galp-(1----3)-beta-D-Galp-(1----3)-beta-D-Ga lp-(1----3)-beta-D-G-alp-(1----3) beta-D-Galp-(1----4)-D-Glc.
