| Research Abstract |
Microbial metabolisms specific to microaerobic conditions were investigated mainly utilizing DNA microarray. Pseudomonas aeruginosa, anoxygenic photosynthetic bacteria, and thermophilic hydrogen oxidizing bacterium were used as research materials. The regulatory mechanism of multiple energy metabolisms especially for terminal oxidases and the transcriptional regulators that mediate the regulation were clarified. We also found a novel functional diversification mechanism of high affinity terminal oxidase in P. aeruginosa.
