Fig. 1From: Saccharomyces cerevisiae employs complex regulation strategies to tolerate low pH stress during ethanol productionBatch fermentation of KF-7 (square), B3 (diamond), C3 (triangle), and BC3 (circle) in the conditions of pH 4.5 (solid line) and pH 2.5 (dotted line). Total cell number (A) and the concentrations of glucose (B), ethanol (C), and glycerol (D) were measured. The average values and standard derivations (error bars) of three independent experiments were presentedBack to article page
