At Lund University, Division of Food and Pharma, researchers studied the role of annealing in the freeze-drying of probiotic bacteria. Using the INFORS HT Multifors bioreactor and eve software, they controlled the fermentation of Limosilactobacillus reuteri to produce consistent cell cultures for downstream drying. Their results show that increased annealing time leads to thicker encapsulating structures and enhanced storage stability, providing a clearer path to developing more robust probiotic products.

At the University of Boras in Sweden, researchers have scaled up second-generation bioethanol production from beech wood chips using an acetone-based organosolv fractionation process. With the help of the INFORS HT Multifors bench-top bioreactor, they confirmed high fermentation efficiency at the 10-L scale, reaching ethanol yields of up to 95% from glucose-rich C6 streams. This study illustrates how optimized biomass pre-treatment and fermentation workflows can drive more efficient and scalable biofuel production.

In a study from the University of Aveiro, researchers leveraged the INFORS HT Minifors bench-top bioreactor to optimize recombinant laccase production in Komagataella phaffii.
