1.12.2.1	4	-	4 weeks, atmosphere of N2, air or H2, very little loss of activity	395560	
1.12.2.1	23	-	atmosphere of N2, air or H2, 40% loss of activity after 2 weeks, complete loss of activity after 4 weeks	395560	
1.12.2.1	35	40	at optimal temperature range of 35-40°C, a minimal activity loss during the first 10 to 20 min and thereafter, activity steadily decreases as incubation time increases. After 80 min of incubation, the enzyme loses 75-80% of all of its activity	701586
