Enzymatic synthesis of two novel non-reducing oligosaccharides using transfructosylation activity with β-fructofuranosidase from Arthrobacter globiformis

Two novel non-reducing oligosaccharides together with tri- and tetra-saccharides were synthesized by transfructosylation activity from sucrose as a donor and cellobiose or cellotriose as an acceptor with a purified beta-fructofuranosidase from Arthrobacter globiformis IFO 3062, and these oligosaccharides were identified as O-beta-D-glucopyranosyl-(1-->4)-alpha-D-glucopyranosyl-(1-->2)-alpha,beta-D-fructofuranoside and O-beta-D-glucopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->4)-alpha-D-glucopyranosyl-(1-->2)-alpha,beta-D-fructofuranoside by spectrometric analyses. Both oligosaccharides were stable under condition at 100 degrees C for 30 min, and showed no degradation at pH 2.
