Abstract:
This thesis explores the behaviour of biofilm fermenters through the analysis of two individual biofilm fermentation case studies. The studies were performed in a novel tubular bioreactor with homogeneously controlled shear. The case studies included a two-phase (gas–liquid) study performed on the anaerobic, lactic acid-producing Lactobacillus rhamnosus, and a three-phase (gas–liquid–solid) study on the CO2-fixating, succinic acid-producing Actinobacil-lus succinogenes. The studies focused specifically on four parameters, namely volumetric pro-duction rates, specific production rates, the metabolic product distributions with correspond-ing redox analysis, and the biofilm compositions as a function of shear conditions.
