Microbiology, Biochemistry & the Living Cultures That Transform Food
For millennia, humans have harnessed invisible microbes to transform simple ingredients into bread, beer, wine, cheese, and kimchi. These simulations reveal the hidden world of fermentation—from the Monod kinetics governing yeast growth to the microbial succession in a jar of kimchi. Watch populations rise and crash, acids accumulate, and metabolic pathways light up as glucose becomes ethanol, lactic acid, and flavor.
The mathematical foundations of microbial growth, from Monod’s saturation kinetics to Arrhenius temperature dependence. Watch how substrate, temperature, and toxicity shape fermentation curves.
Monod kinetics in action: watch Saccharomyces cerevisiae grow through lag, log, and stationary phases as glucose depletes and ethanol accumulates in a virtual fermenter.
Run parallel fermentations at 5 different temperatures. See the Arrhenius curve, the Q10 rule, and the deadly cliff where enzymes denature beyond the thermal death point.
Compare bread, wine, champagne, and turbo yeast strains as they poison themselves with their own ethanol. Watch viability crash and fermentation stall at each strain’s tolerance limit.
From sourdough starters to kimchi jars, explore the living ecosystems that create the world’s great fermented foods. Each simulation models real microbial populations and pH dynamics.
Feed a virtual sourdough starter and watch LAB and yeast compete over feeding cycles. See pH oscillate between 3.5–5.5 as lactic acid bacteria produce acid and yeasts produce CO2 for rise.
Watch microbial succession unfold: Leuconostoc dominates early, then Lactobacillus plantarum takes over as pH drops. Adjust salt, temperature, and spice to shape the final community.
Age Brie, blue cheese, or cheddar in a virtual affinage cave. Watch surface mold grow, proteolysis soften the paste, and flavor complexity build over weeks of careful temperature and humidity control.
The science behind beer, wine, and kombucha. From yeast strain selection to malolactic softening, these simulations reveal the biochemistry that makes great beverages.
Watch a SCOBY pellicle form as Acetobacter weaves cellulose nanofibers at the tea surface. See the symbiotic dance: yeast below produces ethanol, bacteria above converts it to acetic acid.
Brew with ale, lager, or Belgian yeast. Watch gravity drop, ABV rise, and flavor compounds (esters, fusels, diacetyl) form. Choose your pitch rate, OG, and temperature for the perfect brew.
Watch Oenococcus oeni convert sharp malic acid to soft lactic acid in wine. See individual molecules transform as the diacetyl peak rises and falls, adding buttery complexity to your virtual Chardonnay.
The molecular-level view: glycolysis, pyruvate branching, and the fundamental metabolic pathways that power all fermentation.
