Soil catalase (S-CAT) is an important enzyme of soil microbial metabolism, which plays an important
role in the removal system of H2O2.
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.
Reagents and Equipment Required but Not Provided.
Table centrifuge, transferpettor, spectrophotometer, water bath, 1 mL quartz cuvette, ice and distilled
water.
