Batch and continuous cultivation of Anaerobiospirillum succiniciproducens have been systematically studied for the production of succinic acid from whey. Addition of 2.5 g/L yeast extract and 2.5 g/L polypeptone per 10 g/L whey was most effective for succinic acid production from both treated and non-treated whey. When 20 g/L non-treated whey and 7 g/L glucose were used as cosubstrates, the yield and productivity of succinic acid reached at the end of fermentation were 95% and 0.46 g/L/h, respectively. These values were higher than those obtained using non-treated whey alone (93% and 0.24 g/L/h for 20 g/L whey). Continuous fermentation of A. succiniciproducens at an optimal dilution rate resulted in the production of succinic acid with high productivity (1.35 g/L/h), high conversion yield (93%), and higher ratio of succinic acid to acetic acid (5.1:1) from non-treated whey.
