Isolation, Production, and Characterization of Thermotolerant Xylanase from Solvent Tolerant Bacillus vallismortis RSPP-15

Figure 4

Effect of pH on xylanase production. The flasks were inoculated with culture and were incubated at different pH (4–11) for 48 h at 55°C. For enzyme activity the reaction was assayed at respective pH with buffers (100 mM) at 55°C for 15 min. Error bars presented mean values of ± standard deviation of triplicates of three independent experiments.
