Researchers have demonstrated how Bacillus subtilis BS20 can be optimized as a potent biocontrol agent for agriculture by scaling up antifungal metabolite production. Using the INFORS HT Labfors bench-top bioreactor, the team developed a process model and validated scale-up from 1 L to 10 L fermentation, maintaining high antifungal activity with a zone of inhibition up to 65 mm. This study offers a scalable, sustainable alternative to chemical pesticides through microbial fermentation.

Researchers at the University of Nottingham’s School of Biosciences have advanced vaccine development for Chagas disease by expressing and purifying a key enzyme target, TcPOP, in E. coli using the INFORS HT Techfors-S pilot bioreactor. The purified protein enabled structural and immunological characterization, showing parasite-neutralizing activity in mouse models and providing insights into the conformational dynamics of the enzyme. These findings offer a strong foundation for the development of a targeted, protein-based vaccine candidate for a globally neglected tropical disease.

Researchers from Adamo Foods and the University of Nottingham investigated how nutritional manipulation of fermentation media, specifically the addition of iron (Fe III) and Vitamin B12, impacts the yield, texture, and nutritional profile of fungal mycelium grown for alternative meat applications. Using the INFORS HT Techfors-S pilot bioreactor, the team scaled up production from shake flasks and observed significant increases in bioaccumulation of iron and B12, with up to 97% terephthalic acid yield sustained across multiple cycles. Sensory testing of biomass processed into steaks also revealed changes in texture and flavor, highlighting the importance of bioreactor-based media optimization for developing high-quality, reproducible mycelium-based products.

This study done by BiOinFood, achieved a 50% increase in biomass and a 15% yield improvement by converting babassu flour into single-cell protein through fed-batch yeast cultivation using the INFORS HT Multifors bench-top bioreactor with eve software and the Minitron incubator shaker. With optimized process parameters and continuous feeding, the resulting protein-rich biomass was successfully used in plant-based burger prototypes, demonstrating a promising path for upcycling agricultural byproducts into functional food ingredients.

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.

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.

Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg developed and tested methods to improve the stability and recyclability of a PET-degrading enzyme for plastic recycling. Using the INFORS HT Labfors bioreactor, the team compared several immobilization strategies and found that pH-responsive polymers delivered the best results, retaining about 80% of enzyme activity and enabling up to five PET degradation cycles. In batch reactions, the process achieved more than 97% terephthalic acid yield in less than 14 hours for the first three cycles and about 78% yield in the fifth cycle. These findings support more efficient and scalable processes for enzymatic PET recycling.

This study, published on ScienceDirect, aimed to revolutionize bioproduction by developing a cost-effective, robust, and scalable platform using a novel approach with C. glutamicum and UF-SSL. This research eliminates costly media additives and energy-intensive detoxification steps, paving the way for more efficient and sustainable industrial ethanol production.

A study conducted by LanzaTech, published in Biotechnology for Biofuels, explores how Clostridium autoethanogenum (an acetogenic bacterium) adapts to various hydrogen ratios in its feedstock. The focus of this study is to enhance carbon capture efficiency with a spotlight on CO₂ conversion. This research unveils the metabolic adaptations of C. autoethanogenum and paves the way for innovative bioengineering strategies to maximize CO₂ conversion in industrial applications.

Researchers at the University of Tartu, Institute of Bioengineering used adaptive laboratory evolution (ALE) to evolve Clostridium autoethanogenum into a faster-growing, yeast extract-free strain named LAbrini. This strain demonstrates improved robustness and performance in continuous bioreactor cultures, offering new potential for sustainable production of renewable chemicals and fuels.
