Construction of a genetically-engineered hyper hydrogen-producing strain useful to the future energy-supplying system by hydrogen gas

当然，需要开发一种新的能源供应系统，如氢能，以取代石油能源。本研究试图通过基因工程来激活代谢途径并增强与产氢相关的酶催化功能，从而尽可能地提高细菌的产氢能力。此外，随机突变法和基因芯片法也获得了一些有趣的结果，为进一步提高细菌产氢能力奠定了基础。

It would be certainly required to develop a new energy-supplying system such as hydrogen energy in place of petroleum energy. This study attempted to enhance bacterial hydrogen production as much as possible by genetic engineering which allows to activate a metabolic pathway and to enhance the enzyme catalytic function related to hydrogen production. In addition, some interesting results obtained by random DNA mutation approach and DNA microarray approach would hold great promise for further improving bacterial hydrogen production.
