Coexpression of formate dehydrogenase (FDH) and ribitol dehydrogenase (RDH) in Escherichia coli was used for the synthesis of Allitol from D-psicose. FDH was coexpressed with RDH for continuous NADH regeneration. The results revealed that the optimum conditions for allitol production occurred at pH 7.0 and 30 °C. Allitol reached the maximum yield of 19.2 mg at 2.0% substrate concentration after 48 hours. Using D-psicose as a substrate, allitol was successfully produced using an engineered E. coli coexpressed with RDH and FDH.

Thepsefdh_D221Q gene coding for a mutant formate dehydrogenase (PseFDG_D221Q) from Pseudomonas, which catalyzes the formate oxidation with the simultaneous formation of NADPH, has been expressed in the cells of lysine-producing Corynebacterium glutamicum strains. The psefdh_D221Q gene was introduced into С. glutamicum strains as part of an autonomous plasmid or was integrated into the chromosome with simultaneous inactivation of host formate dehydrogenase genes. It was shown that the С. glutamicum strains with NADP+ -dependent formate dehydrogenase have an increased level of L-lysine synthesis in the presence of formate, if their own formate dehydrogenase is inactivated.
