a Effect of the temperature on the activity of the keratinolytic extracts obtained with Bacillus cytotoxicus LT-1 and Bacillus cytotoxicus Oll-15. b Arrhenius plot obtained by plotting the logarithm of enzymatic activity (Vo) versus inverse of temperature (1/T, in Kelvins); LT-1 (black) and Oll-15 (white). c Effect of temperature on enzyme stability. Residual activity in function of time incubation at 50 °C. Each determination was performed in triplicates, and values represent mean ± SD
