Synthesis of β-D-fructofuranosyl-(2→1)-2-acetamido-2-deoxy-α-D-glucopyranoside (N-acetylsucrosamine) using β-fructofuranosidase-containing Aspergillus oryzae mycelia as a whole-cell catalyst.

Using soft granules consisting of Celite 535 and dried Aspergillus oryzae NBRC100959 mycelia containing β-fructofuranosidase as a whole-cell catalyst, N-acetylsucrosamine [β-D-fructofuranosyl-(2→1)-2-acetamido-2-deoxy-α-D-glucopyranoside] was produced from sucrose and 2-acetamido-2-deoxy-D-glucose by enzymatic transfructosylation. The isolated yield of N-acetylsucrosamine from the reaction mixture was 22.1% (from sucrose).
