Title:
水素生産能力に関する遺伝子を改良された微生物、及びその微生物を用いた水素の製造方法
Document Type and Number:
Japanese Patent JP4746558
Kind Code:
B2
Abstract:
The present invention provides a microorganism which possesses the formate dehydrogenase gene and hydrogenase gene and contains an exogenous transcription activator gene for formate hydrogen lyase system, characterized in that said microorganism shows the transcription activator for formate hydrogen lyase system highly expressed therein and shows an improved function to generate hydrogen from formic acid, and a process for producing hydrogen using the microorganism. Utilization of the microorganism of the present invention enables the hydrogen production from an organic substrate to be accomplished on a practical, commercial scale. The hydrogen to be produced by the present invention, which is free of carbon monoxide being causative to poisoning of the electrode catalyst for fuel cells, is useful as a fuel for fuel cells.
