Levan, fructo-oligosaccharides and fructosyl derivatives were formed from sucrose using recombinant levansucrase from Rahnella aquatilis. Levan formation was optimal at 30 °C resulting 57 % of the theoretical yield. The more suitable substrate concentration for levan formation was 200 g sucrose/L. Oligosaccharides was accumulated selectively at high substrate concentration. The increase of levan and oligosaccharides formation was not achieved by adding water-miscible organic solvents. Alkyl fructosides were synthesized from various alcohols as fructosyl acceptors by R. aquatilis levansucrase. © Rapid Science Ltd. 1998
