Measurement Significance:

Soil nitrous reductase is one of the key enzymes in denitrification, involved in the reduction reaction of nitrite to NO, its activityReflecting the conversion efficiency of nitrogen during biodegradation, providing a certain basis for the study of nitrogen conversion law. Determination Principle: Nitrite reductase can reduce NO2-reduction to NO, so that the S product involved in the diazotization reaction to generate the NO2- reduction of the purple compound, that is, the variation of the absorbance value at 540 nm can beActivity of nitrite reductase in the soil.
Agential Experimental Supplies and Instruments: Balance, visible spectrophotometer, water bath, low temperature centrifuge, 1ml glass cuvette.
