In this work a novel reactor is evaluated on its potential to intensify biobased processing via a novel potentially continuous enzymatic hydrolysis process. An oscillatory flow bioreactor is applied in batch and recirculating mode, the latter mimicking the flow pattern of a continuous process. The recirculating mode operation can intensify cellulose conversion to hydrolyzed sugar liquid significantly, namely with enabling high solid processing and reaching >10% higher cellulose conversion than the respective operation in batch mode. Resulting sugar concentrations reach >90 mg/mL with the potential to enable the elimination of further concentration steps in down‐stream processing, having a positive impact on the overall efficiency and sustainability of further processing steps to biofuels or biochemicals.
