| Outline of Final Research Achievements |
Hydroxylamine disproportionation (HD) is a novel microbial reaction, in which microorganisms produce nitrogen gas using hydroxylamine. We found that pH, temperature, and especially hydroxylamine concentration affects activities of HD. An enzyme responsible for HD reaction was very labile to cell disruption, and thus in-vivo studies need to be carried out.

| Academic Significance and Societal Importance of the Research Achievements |
窒素ガスを生成する微生物代謝経路としてこれまで脱窒および嫌気性アンモニウム酸化反応のみが知られてきたが、第三の経路としてHD反応を同定することは、地球圏での窒素代謝を理解するために必要不可欠である。本研究ではHD反応について基礎的な知見を得た。
