Chlorella sorokiniana possesses two forms of nitrate reductase (EC 1.6.6.1.). One with low activity is present in cells at the end of the light-dark cycle, the other with high activity is present after 1 h of illumination. The two forms can be distinguished by gel electrophoresis, isopycnic centrifugation, assay of the partial reactions and their sensitivity to antibodies, respectively. These differences are discussed with respect to an effect of intracellular nitrate on the activation of nitrate reductase.
盐球藻含有两种硝酸还原酶（EC 1.6.6.1.）。一种活性较低的酶存在于光暗周期结束时的细胞中，另一种活性较高的酶存在于光照 1 小时后。这两种形式可以通过凝胶电泳、等密度离心、部分反应的测定以及对抗体的敏感性来区分。这些差异与细胞内硝酸盐对硝酸还原酶激活的影响有关。
