(A) Fractions of total protein and HRP activity remaining in the supernatant as a function of phenol/H2O2 concentrations; (B) the ratio between active HRP and protein content in the aqueous phase. Initial HRP concentration is 0.1 mM. Initial H2O2 concentration is half of the initial phenol concentrations as shown in the abscissa. Reaction time is 60 min. Error bars indicate the standard deviation of triplicate samples.
