Story summary

Scientists at the Earth-Life Science Institute (ELSI) in Tokyo propose the global constraint principle, which combines the Monod equation and Liebig's law of the minimum to explain how nutrient levels limit cell growth.
The principle shows growth slows as new limiting factors emerge with increased nutrients.
The researchers confirmed their theory with computer models of Escherichia coli (E. coli).
Their findings may enhance microbial production, improve crop yields, and help predict ecosystem responses to environmental changes.
