Fig. 2. Cell growth and xylanase production in S. viridodiastaticus MS9.
MS9 was cultured in LB or LBX broth (LB broth supplemented with 0.3% (w/v) xylan as a carbon source) at 40°C with vigorous shaking. Cell growth was measured at 600 nm, and xylanase activity was measured using the DNS method at 540 nm. ■, cell growth in LB; □, xylanase activity in LB; ●, cell growth in LBX; ○, xylanase activity in LBX.
