Growth and product formation by C. saccharolyticus in pH-controlled batch fermentations with and without N 2 sparging. (A) with sparging (filled symbols) and without sparging (open symbols) growth (▲, Δ) and PH2 (■, □). Product formation in the presence (B) and absence of N2 sparging (C) glucose (♦), acetate (■), lactate (▲), ethanol (●) and PH2 (□).
