Title: Submerged Fermentation of Aspergillus Niger LN0601 to Produce Xylanase
Abstract: The Aspergillus niger LN0601 was used to produce xylanase by submerged fermentation.The influence factors of carbon source,nitrogen source,cultural time,cultural temperature,initial pH,and inoculation volumic fraction of spore suspending liquid on the capability of the stain to produce xylanase were studied.The optimum conditions of Aspergillus niger to produce xylanase are as follows: carbon source 5%(mass fraction) corncob powder,nitrogen source 1%(mass fraction)NaNO3,cultural time 2 d,cultural temperature 28 ℃,initial pH 6.5,20% inoculation volumic fraction of spore suspending liquid added to 250 mL conical flask with 100 mL submerged culture medium,shaking table revolution 150 r/min.Under this condition the xylanase activity could reach to more than 2 000 U/mL.
