Stability and reusability of PHA immobilized enzymes. a Temperature dependency of immobilized enzyme activity. b Thermal inactivation profile of PHA immobilized OPAA4301. c Effect of pH on the activity of immobilized OPAA4301. d pH stability of PHA immobilized enzymes. e The effect of detergents on immobilized OPAA4301. The enzymes were pretreated in solution containing 0.1% of different detergents at 4 °C for 30 min before determination of the residual activity. A single star indicates p < 0.05. f Reusability of PHA immobilized enzymes. The relative activity was defined as the ratio of activity after each cycle to the initial activity
