    摘要： In a step of contacting an organic material including formic acid ions and a carbon source other than the formic acid ions with a microorganism having a formate dehydrogenase gene and a hydrogenase gene under an anaerobic condition, concentration of the formic acid ions in the organic material is set to be not less than 0.01 mol/L and not more than 0.5 mol/L, and concentration of the carbon source is set to not less than 0.1 mmol/L and not more than 200 mmol/L. This allows continuously producing hydrogen for a long time, without dropping the ability of the microorganism to produce hydrogen.
