Bioconversion of D-psicose to D-tagatose and D-talitol by Mucoraceae fungi.
Rhizopus oryzae MYA-2483, which cannot utilize D-psicose as a sole source of carbon, converted D-psicose to two other compounds. These compounds were identified by NMR and IR as D-tagatose and D-talitol. In this study, we describe for the first time the bioconversion of D-psicose to D-tagatose. Various strains of Mucoraceae fungi, to which R. oryzae MYA-2483 belongs, exhibited conversion activity similar to that of R. oryzae MYA-2483. There is the possibility that a considerable number of fungi belonging to Mucoraceae possess such D-psicose conversion activity.
