Latest Patents

Namikawa holds a patent for a methane fermentation process. This process involves cultivating a strain of the genus Methanobacterium in a fermenter that contains essential components such as a carbon source, a nitrogen source, inorganic salts, and micro-flora. The strain exhibits a methanogenic activity above 8.7 × 10^-8 ml/cell.day during the stationary phase of growth. Remarkably, it maintains methanogenic activity even at an oxygen partial pressure of 1/30 atm and can survive under an oxygen partial pressure of up to 1/5 atm. The seed of the strain is cultivated anaerobically in a culture medium with nitrogen sources, inorganic salts, and reducing agents at a mesophilic temperature range of 25°C to 45°C, utilizing substrates like a mixed gas of hydrogen and carbon dioxide, formate, or acetate. The growth of the strain is further enhanced when co-cultured with a strain from the genus Clostridium.
