  • Nucleotide sequence coding for a mannitol-2 dehydrogenase and method for the production of d-mannitol
    Publication number: 20050239180
    Abstract: The invention relates to a nucleotide sequence coding for the mannitol 2-dehydrogenase and a method for producing D-mannitol. Previously known biocatalytic methods for producing D-mannitol yield only small production rates due to the small number of specific activities of mannitol 2-dehydrogenases used for transforming D-fructose into D-mannitol. D-mannitol production can be improved by supplying a nucleotide sequence which codes for a mannitol 2-dehydrogenase having a higher specific activity. Mannitol production can be increased in a particular manner by creating a regeneration system for reduction equivalents by introducing and/or strengthening a formiate dehydrogenase in a microorganism.
