Improved synthesis of hydrogen gas in an organism that has been genetically modified by expression of ferredoxin and oxidoreductase, hydrogen and synthesis and hydrogenase improved activity in an organism that has been genetically modified in the presence of oxygen with the enhanced expression of the E. coli ISC operon

摘要

A recombinant host cell that has been modified to include a heterologous gene at least one, and are selected from the ISC operon gene and the heterologous gene encodes an oxidoreductase and ferredoxin-dependent hydrogenase, the present invention is modified about The recombinant host cell. The invention also relates to a method for producing comprises the steps of making a recombinant host cell is modified such that the steps of culturing in a medium a host cell, and collecting the hydrogen and hydrogen. The invention also relates to modified host cells having high hydrogenase activity by deletion of the gene iscR.
