亚硝酸盐还原酶

该过程中的亚硝酸盐还原酶基因nirS、nirK及一氧化二氮还原酶基因nosZ等被广泛地应用于反硝化微生物多样性研究。

Nitrite reductase genes ( nirS and nirK ) and nitrous oxide reductase gene ( nosZ ) are widely used in the studies of denitrifying microbial diversity .

且外加磁场能够提高亚硝酸盐还原酶的活力，并确定铬（Ⅵ）的去除率与亚硝酸盐还原酶的活力呈正相关。

The Cr (ⅵ) removal rate and nitrite reductase activity were positively correlated with the nitrite reductase activity . Plus a magnetic field can enhance the vitality of nitrite reductase .

通过原位末端检测技术测定前列腺组织细胞凋亡情况；应用亚硝酸盐还原酶法检测前列腺组织中NO变化并计算NOS活力的变化；

We observed apoptosis with terminal transferase deoxyuridine nick-end assays and tested NO of the prostate tissue with nitrite reduction test then calculated the activity of NOS.

对亚硝酸盐还原酶的部分酶学性质进行研究，得出酶反应的适宜温度为28-35℃，最适温度为30℃；酶的热稳定性不好，温度超过40℃，酶活性即损失87.5%。

Enzymatic study of the nitrite reductase show that temperature for enzyme reaction are 28-35 ℃, the optimum temperature is 30 ℃; Thermal stability of the enzyme is not good . So when temperature exceeds 40 ℃, enzyme activity loses 87.5 % .
