Solved via: NRTL.
Bioreactor (Monod fermenter)
A steady-state chemostat: substrate is consumed by Monod growth (μ = μmax·S/(Ks + S)) to produce biomass — a modern reactor model legacy tools lack.

View & openMedia-prep + Monod fermenter
A production bioprocess step: the growth medium is preheated to fermentation temperature, then a Monod chemostat consumes the substrate to build biomass — the media conditioning + fermentation train around the reactor.

View & openPrecision fermentation (alternative protein)
A continuous chemostat runs Monod growth kinetics with a nonzero product yield — biomass growth and a secreted target protein, the reactor model precision-fermentation/cellular-agriculture scale-up runs on, not just the biomass-only chemostat the other bioreactor examples show.

View & openLignocellulosic ethanol — pretreatment + enzymatic hydrolysis + real fermentation
The bioresource-engineering gap this closes: two existing 'corn-ethanol' showcases in this catalog (superheated-steam-drying-loop, bioethanol-mvr-stillage) are both downstream-only — drying and distillation on an already-fermented feed or a generic surrogate solid, with no bioreactor anywhere in either flowsheet. This is the first biofuel showcase that actually runs a real fermentation: pretreatment (dilute-acid/steam) solubilizes part of the lignocellulosic feed into fermentable sugars, the existing generic enzymatic_reactor (Michaelis-Menten) saccharifies the cellulose fraction left behind, and the existing bioreactor (Monod chemostat) ferments the resulting sugar to ethanol — the real kinetics kernel, not a spec-based separator standing in for the biology. Bounded, and stated plainly: the pretreatment conversion fraction (hemicellulose → sugar) is a caller-specified design input — a measured/vendor yield, not a predicted dilute-acid severity-factor (log R0) correlation; inventing one would fabricate exactly the number this flowsheet's answer depends on. Real lignocellulose chemistry (cellulose, hemicellulose, xylose, glucose) carries no enthalpy or density data anywhere in MaximaLabs's thermo databank — every sugar was checked directly and none has a liquid-density or ideal-gas-Cp correlation, so a flowsheet naming them by their real identities cannot solve at all. Real, differently-named organics with full databank coverage stand in 1:1 instead (glycerol for the lignocellulosic solid, acetic acid for the hemicellulose-derived sugar liquor, methanol for glucose) — the same generic-surrogate posture already established elsewhere in MaximaLabs (e.g. ethanol standing in as the dissolved substrate in the perfusion-bioreactor tests). Ethanol itself is the one real target molecule in the chain — no surrogate needed. Kinetic constants (mu_max, Vmax, Km, yields) are illustrative, not fit to a published fermentation study — the same posture the LHHW methanol-synthesis showcase states for its own rate law. The pentose-sugar liquor from pretreatment is not fermented in this showcase (many industrial processes do not ferment it with ordinary yeast either) — it reports to its own product stream rather than being silently discarded. No downstream distillation is attempted: a rigorous VLE column needs every component priceable, and the fermentation broth carries an unpriced 'biomass' pseudo-component (the same class of limitation this session's Gibbs-reactor work hit with elemental carbon) — ethanol recovery is the documented next real step, not modeled here.
