The thermal stability profile of protease (Fig 3D) indicate that enzyme was stable after 120 min retaining 96.1%, 92.1% and 83.6% of initial activity at 45°C, 50°C and 60°C, respectively. The enzyme was satisfactory stable at temperature range 60-80°C and retained 74.3% and 62.4% of its initial activities after 120 min at 70°C and 80°C, respectively.
