Abstract
To understand the mechanisms underlying the increased N2O reductase activity in the Bradyrhizobium japonicum 5M09 mutant from enrichment culture under N2O respiration, we analyzed the expression of genes encoding denitrification reductases and regulators. Our results suggest a common regulation of nap (encoding periplasmic nitrate reductase) and nos (encoding N2O reductase).
摘要
为了理解从 N2O 呼吸富集培养的中华根瘤菌 5M09 突变体中 N2O 还原酶活性增加的机制，我们分析了编码反硝化还原酶和调控因子的基因表达。我们的结果表明 nap（编码周质硝酸盐还原酶）和 nos（编码 N2O 还原酶）的表达受到共同调控。
