硝酸盐还原酶(NAR)1. However,no remarkable correlation could be found between the nitrate-reductase(NAR) activity and nitrogen removal. d-1条件下,系统对COD,NH3-N,TN,TP的去除率达到了90%以上,具有良好的脱氮除磷效果;②系统内部中层和底层的脲酶活性均与系统的TN去除率显著正相关,底层的亚硝酸盐还原...
Nap and Nar nitrate reductases are enzymes involved in the process of nitrate reduction in bacteria. Nitrate reduction is a crucial step in the nitrogen cycle, where nitrate is converted into nitrite and ultimately into ammonia. This process is essential for the growth and survival of many bacter...
(2)将narG基因中断载体pDGLSpTS电激转化至反硝化菌DNF409中,经过抗性筛选得到表型为SmrKan8的narGHIJ部分基因敲除双交换菌株,并通过PCR分析证实narGHIJ部分基因已经在正确位置通过双交换实现敲除。(3)双交换敲除菌株接入富含硝酸盐及亚硝酸盐的模拟污水中进行反硝化作用实验,发现ZLl50硝酸盐的还原能力相吃DNF409下降...
