Fig. 3From: l-Lactic acid production from glucose and xylose with engineered strains of Saccharomyces cerevisiae: aeration and carbon source influence yields and productivitiesThe influence of carbon source and aeration conditions on YLA (black bars), YEtOH (grey bars) and QLA (empty circles) in IBB14LA1 (a) and IBB14LA1_5 (b). Experiments were conducted in glucose-(YG) or xylose-(YX) based media under aerobic (_AE), anaerobic (_AN) or microaerophilic (_MA) conditions, as indicated. Data for YX_AE (marked with asterisk) were determined for 41 h of conversion time, before lactic acid uptake started (Fig. 5a and Table 1). Data for YX_MA (marked with double asterisk) represent parameters for phase II of the bioreactor conversion (Fig. 6 and Table 1). Data and error bars represent the mean values and the spread of biological duplicates. Data for YG_AE, YG_AN and YX_AN were taken from [20]Back to article page
