LITERATURE
25
-
the enzyme remains fully active at pH 5.0 for more than 15 min at 25°C
25 - 90
-
at 90°C, the catalatic activity is 20% greater than at 25°C. Peroxidatic activity declines after incubation at temperatures higher than 40°C, although at 70°C nearly 50% of the activity at 25°C is retained
30 - 51
-
the enzyme is stable for 30 min up to 30°C and loses 50% of its activity at 43°C, 10 min at 51°C result in complete inactivation of the enzyme
40
-
sharp decrease in activity above
40 - 60
-
the catalatic activity of the enzyme is stable for 24 h at 40°C. At 50°C the half life is about 18 h, while at 60°C over the first 4 h of incubation 50% of activity is observed
40 - 65
95% loss of catalase activity after 22 h at 40°C, 95% loss of catalase activity after 330 min at 45°C, 95% loss of catalase activity after 48 min at 50°C, 95% loss of catalase activity after 15 min at 55°C, 95% loss of catalase activity after 8 min at 60°C, 95% loss of catalase activity after 1 min at 65°C
