Title: Studies on the Xylanase Producer Aspergillus niger X-1 on the Liquid Fermentation Technology
Abstract: Objective:To improve the yield of the Xylanase by Aspergillus niger X-1.Method: Based on the single-factor experiments and orthogonal test,xylanase production by Aspergillus niger X-1 was carried out under liquid fermentation process.Result:The culture medium and the cultivation conditions were optimized as follows: corn cobs 3%,gluose 0.5%,peptone 1%,KH2PO4 0.5%,MgSO4·7H2O 0.1%,Tween-80 0.1‰,pH 6.5,shaking flask speed 200r/min at 30℃ for 120h.Conclusion:The xylanase activity was up to 1 630.78U on the optimized liquid fermentation process and 125.05% higher than the original(724.63U).
