Abstract:

In this manuscript,effect of four phenolic acids,including ferulic,coumaric,salicylic and tannic acid,on the activity of xylanase was investigated through determination of reducing sugars releasing from xylans.The results showed that 0.75 mg/mL ferulic,coumaric and salicylic acid could increased the activity of xylanase by 65.59%,46.21% and 12.83%,respectively.However,tannic acid was found as inhibitor of xylanase,and the activity decreased 37.18% when 0.50 mg/mL was presented.The results of enzyme kinetics showed that these phenolic acids increased the affinity of xylanase for the substrate.The reaction speed increased with coumaric acid added,and significantly reduced by tannic aci
