Abstract: A microorganism suitable for production of hydrogen that is a Thermoanaerobacterium thermosaccharolyticum strain with an accession number of FERM BP-10793, or its mutants.

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.

Abstract: The hydrogen fermentation apparatus is the one that generates hydrogen by decomposing organic matter through hydrogen fermentation. There are arranged a hydrogen fermentor which holds the treating liquid containing organic matter, and a string-shape carrier which is positioned to immerse itself in the treating liquid in the hydrogen fermentor, and on which hydrogen-generating bacteria are fixed.

Abstract: In a fly-back transformer, the tertiary winding for obtaining the secondary B power source is wound in a position where the coupling with the primary winding is weak and where it interlinks the leakage flux of the secondary winding with the primary winding, and the output of the tertiary winding is rectified during the scanning period of a horizontal deflection circuit of a television receiver. Accordingly, only the wave crest value of the ringing is made smaller, regardless of the shot pulse to be obtained within the secondary winding.
