  1. C. shehatae had significantly lower concentrations of peroxidase or catalase activity when compared with other yeast assayed for in this study.
  2. Data expressed as nmol of NADPH oxidised per minute per mg of protein for peroxidase activity and nmol formaldehyde produced in the presence of hydrogen peroxide for catalase activity.
