Summary: The study investigated internal mass transfer effects in biofilm fermentations of Actinobacillus succinogenes, with resuspended free cell fermentations showing faster production rates than attached biofilms runs. Biofilm effectiveness factors initially ranged from 75% to 97%, but increased with progression of batch operation due to increased succinic acid titres. This research emphasized the importance of considering internal mass transfer in biofilm fermentations involving A. succinogenes to optimize productivities.

Summary: This study explored the use of ozonation and alkaline pretreatments to enhance the release of fermentable sugars from cassava rhizomes. The results showed that alkaline pretreatment achieved higher lignin removal and glucose utilization compared to ozonation pretreatment. Fermentation of the alkaline-pretreated cassava rhizome resulted in the highest succinic acid concentration. This research provides an alternative option for converting cassava rhizomes into biochemical products in biorefineries.
