Abstract |
Three sequential fermentative batches were carried out with cell recycle in four simultaneously operating bioreactors maintained at pH 6.5, 30°C, and 100 rpm. P. acidipropionici ATCC 4875 was able to produce propionic and succinic acid from sorbitol. The concentration of propionic acid decreased slightly from 39.5 ± 5.2 g L(-1) to 34.4 ± 1.9 g L(-1), and that of succinic acid increased significantly from 6.1 ± 2.1 g L(-1) to 14.8 ± 0.9 g L(-1) through the sequential batches. In addition, a small amount of acetic acid was produced that decreased from 3.3 ± 0.4 g L(-1) to 2.0 ± 0.3 g L(-1) through the batches. The major yield for propionic acid was 0.613 g g(-1) in the first batch and succinic acid it was 0.212 g g(-1) in the third batch. The minor yield of acetic acid was 0.029 g g(-1), in the second and third batches. |
