Figure 3From: Optimization of upstream and downstream process parameters for cellulase-poor-thermo-solvent-stable xylanase production and extraction by Aspergillus tubingensis FDHN1 Optimal temperature (A) and thermal stability (B) of the xylanase from A. tubingensis FDHN1. Xylanase activity was measured at different temperatures to determine its optimal range. For the determination of thermal stability, the residual activity of the xylanase was measured after 30, 60, 90 and 120Â min pre-incubation at different temperatures.Back to article page
