摘要： The invention relates to a cellobiose phosphorylase, which catalyzes, among other things, the synthesis of cellobiose from glucose 1-phosphate and glucose. The cellobiose phosphorylase according to the invention can be understood as a mutation of the cellobiose phosphorylase from Cellulomonas uda. In comparison to cellobiose phosphorylase of the wild type, the cellobiose phosphorylase according to the invention is distinguished by improved activity and process stability, in particular temperature stability, and lower product inhibition and therefore is especially suitable for use in industrial processes.

摘要： The invention relates to a process for the synthesis of a product saccharide, preferably of D-allulose from an educt saccharide, preferably from D-fructose under heterogeneous or homogeneous catalysis which includes chemical and/or enzymatic catalysis. The synthesis is performed in at least two reactors that are arranged in series and the reaction product exiting the first reactor is subjected to chromatographic separation before it enters the second reactor. Preferably, the chromatographic separation is integrated in a simulated moving bed.

摘要： The invention relates to a saccharose phosphorylase that catalyzes the synthesis of glucose-1-phosphate and fructose from saccharose and phosphate, among other things. The saccharose phosphorylase according to the invention can be considered to be a mutation of the saccharose phosphorylase from Bifidobacterium adolescentis. In comparison to wild-type saccharose phosphorylase, the saccharose phosphorylase according to the invention is distinguished by improved activity, process stability, temperature stability, and lower product inhibition and is therefore particularly suitable for use in industrial processes.
