Determination of Significance：
Soil catalase (S-CAT) is an important enzyme of soil microbial metabolism, which plays an important role in the removal system of H2O2.
Measurement Principle：
Since the absorbance at 240 nm is proportional to the amount of H2O2, the activity of S-CAT can be quantified by measuring the decrease in the absorbance of the reaction solution at 240 nm.
Self Provided：
