Using Different Concentrations Of Some Agricultural Wastes as a Carbon Source For The Production of Xylanase Enzyme

Abstract

xylan extracted by dilute acid treatment from papyrus was used as a carbon source to produce xylanase enzyme in five concentrations of 0.1, 0.3, 0.5, 0.7 and 0.9%. the highest production of xylanase was at a concentration of 0.5%, with an enzyme activity of 2800 U/ml, then a concentration of 0.7% with an enzymatic activity of 2520 U/ml, then concentrations of 0.9, 0.3 and 0.1% with an enzymatic activity 0f 2360, 2280 and 1280 U/ml, respectively. Under production conditions, the rotor was incubated in front of the vibrating incubator at 150 rpm and at a temperature of 37 C for 48 hours.
