  • Patent number: 8227222
    Abstract: The hydrogen-producing method of the an aspect of the present invention is a method for producing hydrogen in which hydrogen is produced from an organic matter using a microorganism, characterized by using pellets on which hydrogen-producing acid-resistant bacteria are entrapped and immobilized, producing hydrogen by bringing the pellets into contact and react with the organic matter in an environment of a pH of 4 to 6. The inventors of the present invention have obtained a finding that a hydrogen-producing bacteria are entrapped and immobilized, so that the optimum pH of the hydrogen-producing bacterium shifts to low range. The present invention is made based on the above finding and uses pellets on which the hydrogen-producing bacteria are entrapped and immobilized, so that the hydrogen-producing bacterium is activated at a low pH range of 4 to 6 to produce hydrogen. Therefore, the effects of contaminated bacteria that consume hydrogen are less, and the yield of hydrogen can be improved.
