Fig. 2

Growth and xylanase production in thermophilic bacteria VSDB5 (a) and KBFB4 (b). Growth is expressed as a measure of OD at 600 nm, depicted as a continuous line (orange), and xylanase activity in IU mL⁻¹ is depicted as dotted lines (purple). The maximum activities for KBFB4 and VSDB5 were 0.76 and 1.0 IU mL⁻¹ at 6 and 12 h after inoculation, respectively. The standard deviation was not more than 5% from the mean
