Cultivation of C. cellulovorans with SBP and Avicel. a Total sugar concentration after 11-days cultivation in the culture with SBP (left) and Avicel (right), where negative control (open bar), C. cellulovorans (closed bar) are included. b Cell growth in the culture with SBP (left) and Avicel (right). c Organic acid concentration in the culture with SBP (left) and Avicel (right), where lactic acid (Δ), acetic acid (*), butyric acid (black filled circle) are included. d Reduced sugar concentration in the culture with SBP (left) and Avicel (right). e Gas production after 11-days cultivation in the culture with SBP (left) and Avicel (right), where H2 (closed bar), CH4 (hatched bar), CO2 (open bar) are included. Values indicate increments from the volume of negative control and are calculated as the volume per one kg of dry weight of substrates. Values with error bars are mean ± SE of three independent samples. An asterisk indicates a significant difference (p < 0.05)
