Effect of temperature shift on production of xylanase by Aspergillus niger
The effect of incubation temperature on xylanase production by Aspergillus niger was investigated. The fermentation time and maximum xylanase activity decreased with increasing the temperature. In steady-state condition the optimum temperature was 28 °C and 92 h were required to obtain the maximum xylanase activity. The unsteady-state operation by shifting the temperature from 33 °C for biomass growth to 27 °C for xylanase production significantly reduced production time without any adverse effect on xylanase activity.
