Results of the continuous cultures of C. saccharolyticus and C. owensensis performed in the continuously stirred tank reactor (CSTR). (A) Q _H2, line graph (mmol · L⁻¹ · h⁻¹) and H₂ yield, bar graph (mol · mol⁻¹)_; (B) substrate conversion rate (mmol · L⁻¹ · h⁻¹); (C) Optical density (OD) measured at 620 nm, line graph, and biomass yield, bar graph (mol/mol) from planktonic phase; and (D) lactate productivity (mmol · L⁻¹ · h⁻¹), line graph, and lactate yield (mol · mol⁻¹), bar graph. Case A (open circles, filled bar); Case B (filled circles, dotted bar); Case C (open triangles, bar with vertical lines); and Case D (filled triangles, bar with skewed lines). Substrate loading rate, solid black line with open squares.
