密閉内における-酸化炭素の消滅について

There are pnenomena that the atmospheric CO concentrations of sealed areas decrease rapidly compared with other gases concentrations are kept almost unchanged. Then, causes of these phenomena were tried to be resolved. The result clarified that the CO concentration emitted from a coal sample decreased rapidly when the coal sample was wet adequately with no relation to its inherent moisture and kept at an appropriate temperature. However, the CO concentration did not decrease rapidly in such an atmosphere as bacteria were not alive. Therefore, it was clear that the phenomena were attributed to bacteria regardless of coal itself.
