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.
