Tools & Code

Open source tools and code developed in the Cremer Lab.

ElectronFlow — Interactive Redox Tower
ElectronFlow — Interactive Redox Tower
Python · 2026
Interactive redox tower companion to Scarampi, Cremer & Soyer, Community metabolism in dynamic redox landscapes (Current Opinion in Microbiology, 2026). Adjust pH, gas partial pressures, and metabolite concentrations to see how reduction potentials shift and which microbial metabolisms are thermodynamically feasible. Runs entirely in the browser.
