Batch fermentation (pH 7, 45% CO2 gas at 0.04 vvm) using glucose (40 g L-1) resulted in SA titer, 26.7 g L-1; productivity, 3.33 g L-1h?1; yield, 0.621 g g?1. Fed-batch mode with cyclic extrication of SA from the medium markedly enhanced the yield to 0.699 g g?1 and concentration to 59.5 g L-1. Batch fermentation using sugars derived from Chlorella vulgaris ESP-31 without yeast extract gave a SA productivity, concentration, and yield of 1.82 g L-1h?1, 36.1 g L-1, and 0.720 g g?1, respectively. Furthermore, continuous fermentation (at 6 h HRT) with microalgal sugar improved the productivity and yield to 3.53 g L-1h?1 and 0.62 g g?1, respectively, which is comparable to those obtained by using glucose. This study reports the highest productivity for SA fermentation using microalgae-derived sugars. ? 2021 Elsevier Ltd |
