Outline of Final Research Achievements

The aim of this study is to understand the genetic, physiological and ecological basis of thermophilic carboxydotrophs that can grow on carbon monoxide for construction of a modern sustainable low carbon technology. Main results of this study are as follows. We successfully isolated novel thermophilic carboxydotrophs from hydrothermal environments and revealed diverse CO metabolism through de novo genomic and transcriptional analysis. In addition, we demonstrated that various carboxydotrophs widely distributed domestic hydrothermal environments and unveiled the microbial community structures of those environments in detail.
