fermSYS VOC-Buddy for making water kefir with intelligent fermentation control
fermSYS Buddy: Dynamic Bioprocess Control for Water Kefir
Discover how the fermSYS Buddy transforms water kefir fermentation from static recipes into an intelligent, automated bioprocess. By connecting the compact fermSYS CUBE to a dosing pump via ad-hoc Wi-Fi, it enables real-time feedback and PID-controlled dynamic feeding. Combining biotechnology, AI, and smart hardware optimizes substrate use, enhances taste consistency, shortens production times, and leads the way to aut

From Soft Sensors to Autonomous Fermentation Control: Scaling Intelligent Strategies with fermHUB
How can we make fermentation processes more transparent, intelligent and autonomous? In her Bachelor’s thesis at Westphalian University of Applied Sciences, a student combines a fermSYS VOC sensor with an external turbidity sensor to develop a soft sensor for cell viability. The next step: using fermHUB to turn online process insights into intelligent control strategies for a future of autonomous fermentation.

Development of sustainable bioprocesses at ETH Zurich using fermSYS – VOC sensors
At the Vorholt Lab (Institute of Microbiology, ETH Zurich), researchers are engineering *Escherichia coli* to efficiently utilize green methanol as a sustainable one-carbon feedstock. Using the fermSYS VOC sensor for real-time methanol monitoring, the team gains continuous process insights that accelerate strain development and optimize fermentation strategies—advancing sustainable biomanufacturing and supporting the transition to a circular carbon economy.

Accelerated bioprocess development with Kuhner TOM and fermSYS – VOC sensors
Media screening is no longer just about biomass, O₂ and CO₂. By combining the Kuhner TOM system with the fermSYS fermSENSE – MULTI FLOW, volatile organic compounds (VOCs) provide real-time metabolic insights, revealing by-product formation and cellular stress long before endpoint analysis. More data, better decisions, faster process development – transforming a shaker into an intelligent mini-bioreactor.

Smart fermentation for aquaculture: How a VOC sensor could revolutionize the production of innovative tilapia vaccines
Smart fermentation for aquaculture: How a VOC sensor could revolutionise the production of innovative tilapia vaccines.
In a current development project by W42, artificially designed antigens against two viral fish pathogens are being produced.
What makes this special is that:
The yeast cells themselves are used directly as a component of fish feed following fermentation.
The VOC sensor provides additional information about the physiological state of the culture.

From Assumption to Data-Driven Fermentation
How the Bioprocess Owner Reclaims Their Day. For years, the daily routine in fermentation production looked the same: put on safety glasses, glove up, walk to the fermenter, take manual samples, bring them to the lab, wait for results—and still make decisions with a degree of uncertainty. What is really happening inside the bioreactor right now? How is the biomass evolving? Are the cells still viable? And most importantly: when is the right moment to intervene? Those days are
