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

Figure 7

Effect of different nitrogen sources on xylanase production. The control flask does not contain any nitrogen sources. Test flasks contained different nitrogen sources in the medium at a level of 0.5% (w/v). The flasks were inoculated with culture and incubated at 55°C for 48 h at pH 7.0 with 1.0% birch wood xylan. Error bars presented mean values of ± standard deviation of triplicates of three independent experiments.
