Study on next-generation technology for production of oil independentenergy and new materials based on deep-sea hydrothermal environments.

这项研究的最终目标是构建一个基于深海热液环境的下一代技术平台，用于生产独立于石油的能源和新材料。本研究的主要结果如下：我们表征了来自超嗜热微生物的新型氢化酶，并成功地利用其固定化酶生产氢气。我们还分离了一种新型的超嗜热微生物，该微生物可以利用一氧化碳进行生长，并开发了其一氧化碳脱氢酶的表达系统，该酶可催化一氧化碳和二氧化碳的可逆反应。

The ultimate goal of this study is construction of a platform towards next-generation technology for production of oil independent energy and new materials based on deep-sea hydrothermal environments. Main results of this study are as follows: We characterized novel hydrogenases from hyperthermophilic microorganisms and succeeded in hydrogen production using their immobilized enzymes. We also isolated a novel hyperthermophilic microorganism that could utilize carbon monoxide for its growth and developed expression system for its carbon monoxide dehydrogenase that catalyze reversible reaction of carbon monoxide and carbon dioxide.
