The catalase and peroxidase activity in the GtoCFEs prepared from aerobically and anaerobically cultivated G. toebii. The breakdown H2O2 with aerobically prepared GtoCFE (closed circle) and anaerobically prepared GtoCFE (closed square) was directly monitored at absorbance 240 nm for 120 s under 25°C, respectively. The results represent the mean (± standard deviation) of five independent measurements.
