Xylanase activity from Cellulomonas flavigena extracts as affected by temperature and its degradation under in vitro ruminal conditions

2 = 0.93, P < 0.0002). As temperature was raised, the ammonia nitrogen concentration was increased (linear P < 0.001, quadratic P < 0.01), and the half time of degradation was reduced (linear P < 0.001, quadratic P < 0.01). The mean degradation half time was 23.95 h, which showed that the xylanolytic enzymes from C. flavigena CDBB-531 degraded slowly indicating that they have the potential to be evaluated as exogenous enzymes for ruminants.
