From: An organic acid-tolerant HAA1-overexpression mutant of an industrial bioethanol strain of Saccharomyces cerevisiae and its application to the production of bioethanol from sugarcane molasses

Figure 4

Ethanol production of S. cerevisiae ER and ER HAA1-OP in molasses medium (a) and molasses medium containing 0.5% acetate (b). Strains ER and ER HAA1-OP were inoculated in molasses medium (100 ml in a 300-ml Erlenmeyer flask) containing 0% or 0.5% acetate (pH 4.5). The initial densities of the yeast cells were 4.8 × 107 (equivalent to OD600 = 1). The cultures were incubated at 30°C for 24 h with shaking at 80 rpm. The data presented in this figure are averages from three independent experiments. Error bars represent standard deviations.
