Energy-translation coupling limits anaerobic yeast growth (opens in new tab)

Understanding how nutrient-specific limitations shape anaerobic metabolism in Saccharomyces cerevisiae is essential for defining the physiological limits of yeast growth. Integrating chemostat physiology, multi-omic profiling, and targeted metabolic engineering under strictly anaerobic conditions, we show that yeast maintains a conserved maximum glucose uptake (~14 mmol/gDW/h) under carbon (C), nitrogen (N), and phosphorus (P) limitation, while distinct regulatory bottlenecks constrain maxima...
