Determination of Significance:
S-NR catalyzes the reduction of nitrate to nitrite in soil, which is the key enzyme of nitrate reduction in soil. Study on the activity of S-NR is of great significance for rational fertilization and reduction of nitrogen loss.
Measurement Principle:
S-NR catalyzes the reduction of nitrate to nitrite, NO3-+NADH+H+→NO2-+NAD++H2O; the generated nitrite can quantitatively generate red azo compounds with p-aminobenzenesulfonic acid and α-naphthylamine under acidic conditions; The unreacted NADH will inhibit the subsequent color reaction, and then carry out the subsequent reaction with PMS; the generated red azo compounds are 520 nm has a maximum absorption peak, which can be determined by spectrophotometry.
Self Provided:
Spectrophotometer, water bath, low temperature centrifuge, 1ml glass cuvette, distilled water, 30 mesh sieve (or smaller), ice and distilled water.
