Production, Purification, and Characterization of a Major Penicillium glabrum Xylanase Using Brewer's Spent Grain as Substrate
Figure 2
Effect of initial pH (a) and temperature (b) on xylanase production by P. glabrum. Culture conditions: Vogel medium with 1% (w/v) brewer’s spent grain under stationary condition for six days at 28 °C (a) and pH 5.5 (b). (■) Xylanase activity (U/mL), (•) intracellular protein (mg).
