a The xylanase activity and pH change after incubating wheat straw with Pseudomonas boreopolis G22 for 5–25 days, and b effects of different pH values on xylanase activity in Pseudomonas boreopolis G22. The 1.0% wheat straw biomass was incubated with G22 strain at 30 °C with agitation at 200 rpm for 5–25 days. The supernatants from 5 days of incubation were used to assay the effects of different pH values on xylanase activity. Values represent mean ± SDs (n = 4). Bars with different letters indicate significant differences at p < 0.05 according to Duncan’s multiple range tests
