Cultivation of C. cellulovorans, CCeM and MFMP with SBP. a Total sugar concentration after 11-days cultivation in the culture with SBP, where negative control (open bar), CCeM (closed bar), MFMP (dotted bar) are included. b Cell growth in the culture of CCeM and MFMP with SBP, where CCeM (open circle), MFMP (closed circle). c Organic acid concentration in the CCeM (left) and MFMP (right) cultures with SBP, where lactic acid (Δ), acetic acid (*), butyric acid (black filled circle) are included. d Gas production after 11-days cultivation in the CCeM (left) and MFMP (right) cultures with SBP, 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 SBP. e pH after 11-days cultivation with SBP, where negative control (open bar), C. cellulovorans (hatched bar), CCeM (closed bar), MFMP (dotted bar) are included. f Concentration of reducing sugar in the CCeM and MFMP cultures with SBP, CCeM (closed circle), MFMP (open circle). Values with error bars are mean ± SE of three independent samples. An asterisk indicates a significant difference (p < 0.05)
