Coupling of permeabilized cells of Gluconobacter oxydans and Ralstonia eutropha for asymmetric ketone reduction using H(2) as reductant.
A combined two-cell reaction system containing Gluconobacter oxydans and Ralstonia eutropha was evaluated with regard to asymmetric ketone reduction using H(2) as the reductant. Whole cells permeabilized by EDTA/toluene were used, and synthesis was performed in a biphasic aqueous/organic reaction medium. The two-cell system was compared with a system in which G. oxydans alone was used for both ket
