Abstract

La présente invention concerne un procédé d'obtention d'ascopyrone P ou de l'un de ses dérivés. Ce procédé comporte plusieurs temps. (I) On part d'un substrat du type de l'amidon et on le convertit en 1,5-anhydro-D-fructose avec une lyase d'α-1,4-glucane à un pH d'environ 3,8 à 7,0. (II) On traite ensuite ladite 1,5-anhydro-D-fructose avec une 1,5-anhydro-D-fructose-déshydratase et une pyranosone-déshydratase, et éventuellement une ligase d'ascopyrone-P à un pH d'environ 5,0 à environ 7,5.
