Yeast biosensors are described as rapid, visible, cost-effective, real-time, and relatively low-cost compared with conventional chemical analysis methods, and can be integrated directly into fermentation systems.
Genetically engineered yeast biosensors are used to detect contaminants, spoilage organisms, or hazardous compounds during fermentation or in final fermented beverage products.
Further research is needed on robustness, scalability, and regulatory integration to enable broader industrial implementation of yeast biosensors in fermented beverage production.
Saccharomyces cerevisiae is presented as a suitable sensing platform for beverage production because it is generally recognized as safe and aligns with existing production practices.
Timely feedback from yeast biosensor systems could allow producers to intervene early, reduce waste, and enhance consumer safety.
Upon target detection, biosensor yeast can activate reporter outputs including fluorescence, color change, or electrical signal.
Reported yeast biosensors can sense heavy metals, mycotoxins, ethanol levels, or unwanted microbial metabolites.
Despite conceptual promise and encouraging experimental results, yeast biosensors for fermented beverage safety remain mainly at laboratory scale and have not achieved widespread industrial implementation.
Yeast biosensors are being investigated for early detection of spoilage contamination by Brettanomyces and lactic acid bacteria in fermented beverages.
