Production of succinic acid in basket and mobile bed bioreactors -Comparative analysis of substrate mass transfer aspects
The glucose mass transfer in the biosynthesis of succinic acid with immobilized Actinobacillus succinogenes cells has been comparatively analyzed for a bioreactor with mobile bed vs. a stationary basket bioreactor. The process has been considered to occur under substrate and product inhibitory effects. The results indicated that the bioreactor with mobile bed is more efficient for biocatalyst particles with a diameter over 3mm, while the basket bioreactor is more efficient for smaller biocatalyst particles and basket bed thickness below 5 mm. The performances of both configurations of immobilized A. succinogenes cell beds were found to be superior to the column packed bed bioreactor.
