Great for reducing the effectiveness of this enzyme By comparison with control, the concentration of 45% was one of the best concentrations which gave a big difference in reducing the effectiveness of this enzyme, coagulase, for the second enzyme, significant differences were observed to decrease the effectiveness of this enzyme and the concentration was 45%. It was better to reduce the concentration of this enzyme.
