METHODS FOR PRODUCING HYDROGEN GAS USING THERMOCOCCUS SP

摘要

PURPOSE: A method for producing hydrogen gas(H_2) using Thermococcus sp. strain is provided to generate hydrogen of high yield and high purity without harmful by-product. CONSTITUTION: A method for producing hydrogen gas(H_2) using Thermococcus sp. strain comprises: a step of culturing the strain in a medium containing carbon monoxide, formic acid or a salt thereof, or starch at 50-90 Deg.C.; and a step of collecting hydrogen gas. The Thermococcus sp. strain is Thermococcus gammatolerans, Thermococcus barophilus Ch5, Thermococcus sp. DS-1, Thermococcus sp. DT-4, Thermococcus barophilus MP, or Thermococcus sp. AM4.
