Abstract
A gas chromatographic method was used to demonstrate that nitrite can counteract the inhibition by azide of nitrous oxide reductase activity in denitrifiers. This effect explains why azide (and cyanide) can inhibit nitrogen production from nitrous oxide in these organisms but have little effect on nitrogen production from nitrite. Although the physiological basis by which nitrite opposes the action of azide remains unknown, extensive destruction of azide by nitrite can be ruled out as an explanation.
摘要
采用气相色谱法证明，亚硝酸盐可以抵消叠氮化物对反硝化细菌中一氧化二氮还原酶活性的抑制作用。这一效应解释了为什么叠氮化物（和氰化物）能够抑制这些生物体中由一氧化二氮产生氮，但对由亚硝酸盐产生氮的影响很小。尽管亚硝酸盐对抗叠氮化物作用的生理基础尚不清楚，但可以排除亚硝酸盐对叠氮化物的大量破坏作为一种解释。
