AbstractInitial oxygen aeration enabled Actinobacillus succinogenes 130Z(T) to be regarded as a novel type of lactic-acid-producing strain in subsequent anaerobic cultivation. Lactic acid production increased 32-fold, up to the final titers of 135.6 +/- 0.14 g L-1 with an overall yield of 0.96 +/- 0.09 g g(-1) glucose and 2.94 +/- 0.03 g L-1 h(-1) productivity. The metabolites at the end of dual-phase fermentation by 130Z(T) were (in parentheses: the mol end product formed/100 mol glucose) succinic acid (37), acetic acid (69), formic acid (21), and lactic acid (193). Carbon flux distribution shifted toward to lactate in the bi-staged cultivation, where C-3 flux increased and C-4 flux reduced. The enzyme assay revealed that the lactate dehydrogenase (LDH) activity in dual-phase process was nearly 18-fold higher than the values in mono-phase process. (C) 2010 Elsevier Ltd.
