Fig. 5. Effect of co-substrate concentration on reduction of furfural by whole cell catalytic of B. coagulans NL01. Conditions: 42 mM FAL, 5–50 g L−1 glucose, 9 mg (dry weight) per mL microbial cells, 25 mL phosphate buffer (200 mM pH 7.0), 150 rpm, 50 °C; anaerobic reaction for 24 h under the above conditions, with different letters representing significant differences between the treatment means (p < 0.05).
