N2 - Abstract: Actinobacillus succinogenes NJ113 is capable of microaerobic fermentation, which offers the possibility of a novel type of pyruvic acid production. A dissolved oxygen environment with stirring at 300 rpm was a key factor in the fermentative production of a maximum concentration of pyruvic acid. Potassium carbonate (K2CO3) was found to have a role in promoting pyruvic acid production, influencing the concentration of pyruvic acid and production of the by-product succinic acid. The final titer of pyruvic acid production was 36.8±0.1 g L−1 with an overall yield of 0.639±0.056 g g−1 glucose and 3.12±0.03mmol g−1 dry cell weight h−1. Significance and impact of the study: This study is the first to illustrate the advantage of using Actinobacillus succinogenes NJ113 with no genetic modification under microaerobic conditions for the production of pyruvic acid.
