| Research Abstract |
To investigate the abundance of ammonia-oxidizing archaea to be able to fix carbon dioxide in nature, the following experiments were conducted.(1)establishment of ammonia-oxidizing archaea culture ,(2)bicarbonate fixation of ammonia-oxidizing archaea by using stable isotope probing method,(3)transcription involved in fixation carbon dioxide toward low ammonium. These analyses suggested the fixation carbon dioxide by ammonia-oxidiaing archaea in nature.
