Fermentation is the microbial conversion of carbohydrates into alcohols or organic acids through the metabolic activity of yeasts and bacteria. In plant science, fermentation is central to understanding how plant-derived sugars and starches are transformed during food processing, preservation, and flavor development. Researchers study fermentation to improve crop utilization, enhance nutritional profiles of plant-based foods, and explore the biochemical interactions between plant compounds and microbial communities.

Researchers reviewed how water kefir — a fermented drink made with sugar water and fruit — can serve as a model system for understanding the complex microbial communities that drive fermentation, and how advanced genomic tools could help scale up production while unlocking potential health benefits.
Water kefir grains host a relatively simple mixed community of both bacteria and yeasts, making them an ideal model for studying microbial ecology and interspecies interactions in fermented foods.
Industrial-scale production of water kefir is currently hindered by a lack of defined starter cultures and limited understanding of how the microbial community members interact biologically.
Genome-scale metabolic modelling is identified as a promising tool to design functional, defined microbial communities for food fermentation, though key challenges in data integration and regulatory approval remain.
