In this application note, Enzyferm AS compares bioreactor and shaking flask systems for high-temperature aerobic propagation of Kveik yeast. Using the INFORS HT Minifors 2 and Multitron Standard, the study evaluates ease of use, process control, and reproducibility when working with single- and multi-strain cultures at. The results highlight how system choice impacts robustness and consistency in demanding fermentation conditions.

In collaboration with Regenera Moléculas do Mar and Ecovias Cerrado, this application note presents the successful scale-up of a bioluminescent marine strain, Aliivibrio sp. (ref. 1485), using the INFORS HT Minifors 2 bioreactor and eve bioprocess software. The study validated a reproducible cultivation protocol and examined the light-emission kinetics of the strain under controlled conditions. These findings contribute to a deeper understanding of marine bioprocesses and demonstrate how precise bioreactor control supports the development of bioluminescent applications.

Scaling microbial fermentation, when working with bacterial, fungal, or yeast-based systems, from laboratory scale to pilot or commercial production involves many challenges. Whether you are producing bacterial cultures for biopharmaceuticals, yeast for bioethanol production, fungal systems for enzyme manufacturing, or precision fermentation products, understanding these specific challenges and confidently overcoming them is important.

Feeding strategy is one of the most influential variables in any bioprocess. Whether you’re working with bacterial, yeast, fungal, or mammalian cell cultures, how you supply nutrients affects everything from growth rates and yields to oxygen demand and product quality. The choice between batch, fed-batch, and continuous culture depends on your organism, application, and production goals. Fortunately, modern bioreactor systems like those from INFORS HT make it easy to implement any of these strategies at lab or pilot scale.
