  1. The crude enzyme preparation was incubated with different detergents components for 1 h at 40°C and the remaining activity was measured under standard assay conditions. The results are the mean ± S.D. of two independent experiments conducted in triplicate.
  2. a Initial activity = 15 U mL-1 as 100% at 60°C and pH 12.0.
  3. b Initial activity = 100 U mL-1 as 100% at 30°C and pH 9.0.
