after preincubation of the protein at -20 to 45°C, residual activities of 82.7 to 100% are measured. After storage at 50°C, this enzyme shows an activity of about 63.1%, whereas significant enzyme inactivation is observed after incubation at 55°C

-
AldH appears to be stable between 20°C and 50 C but becomes very unstable at or above 50°C
30 - 60
-
the enzyme is stable between 30°C and 50°C, but becomes unstable at 60°C

mutant enzyme S74A and native enzyme, stable
40 - 80
-
the purified enzyme retains 97%, 85%, 71%, and 56% of the original activity, respectively, after incubation at 40, 50, 60 and 70°C for 60 min. The enzyme is inactivated after incubation at 80°C

-
the enzyme shows no obvious loss of activity after heat-treatment at 70°C for 12 h, and more than 60% of the original activity remains after treatment at 80°C for 12 h. The half-life at 90°C is 4 h
