Industrial fermentation

Bee-free honey produced ex vivo by precision fermentation: recombinant bee enzymes (invertase, glucose oxidase) expressed in Pichia pastoris convert a blended plant-sugar and phytochemical base into a vegan, hypoallergenic honey chemically identical to the natural product.

Fermentation-produced lysine, methionine, threonine and tryptophan let feed formulators hit exact amino-acid targets with lower-protein diets, cutting nitrogen excretion — a mature, price-cyclical commodity market where a single producer's price move (Evonik's 2026 MetAMINO increase) ripples through the whole value chain.

Brewing and distillation capacity (250–500 m³ tanks) is being repurposed as a fermentation CDMO platform for recombinant proteins — from beer and spirits to collagen and albumin.

Engineered-microbe cell factories and flavor-house biotech platforms producing flavors and fragrances — fermented vanillin, biosynthetic terpenes and natural-certified fruity molecules — via precision fermentation rather than petrochemicals or extraction.

Contract fermentation manufacturers and specialty seasoning producers supply food brands with fermented bases (yeast extract, enzyme-assisted seasonings, amazake, cultured dairy/soy fractions) as B2B ingredients rather than finished consumer products.

Live bacteria, yeast and mold cultures that kickstart dairy, bakery and brewing fermentation are a mature, still-growing global industry — Novonesis reported 7% Q1 2026 growth led by cheese, IFF's new culture eliminates all curd-washing water, and India's national dairy board now supplies indigenous starter cultures to its largest cooperatives.

Microbial food protein grown by feeding hydrogen-oxidising bacteria a mix of hydrogen, CO2 and oxygen in gas-loop bioreactors — a land-free 'food from air' route now at commercial demonstration scale.

Acetogenic bacteria fix steel-mill and refinery off-gas (CO, CO2, H2) into recycled-carbon ethanol, acetone and sustainable aviation fuel through the Wood–Ljungdahl pathway — operated at commercial scale by LanzaTech licensees (the 210,000 t/yr Shougang plant, the €200M Steelanol plant at Ghent, and LanzaJet's Freedom Pines alcohol-to-jet facility) and extended to non-steel CO2 feedstocks by Cemvita's engineered-microbe platform.

Precision-fermented human milk oligosaccharides — 2'-fucosyllactose, LNnT and sialylated sugars produced by engineered E. coli or yeast — that feed infant-formula bifidobacteria and block pathogen attachment, now expanding from infant nutrition into adult gut-health supplements.

Microbial single-cell protein grown by fermenting methane, CO2/hydrogen or side-streams into a high-protein feed ingredient that displaces fishmeal and deforestation-linked soymeal.

Fungal biomass protein (mycoprotein) and mycelium materials produced via fermentation of Fusarium, Neurospora and Trichoderma — a $4.6B market growing at 12% CAGR.

Genetically engineered microbes as cell factories for proteins, enzymes, HMOs and flavors — a stack from strain design to purified ingredient, at 30–50 g/L target titers.

Recombinant whey, casein and egg-white proteins produced by engineered yeast and filamentous fungi, cutting GHG emissions 90–97% and water use 95–99% versus animal farming.

Microbially fermented fats and oils for food — high-smoke-point fermented cooking oils, microalgae EPA/DHA omega-3 oils, animal-free flavor fats for plant-based meat and dairy, and cocoa-butter-equivalent microbial fats — produced by precision fermentation rather than crops or animals.

Precision fermentation is scaling up intensely sweet, calorie-free plant proteins as sugar replacements — a US platform's third FDA no-questions letter for brazzein, Europe's first commercial-scale brazzein factory under construction in Lithuania, and an Israeli engineered sweet protein clearing FDA GRAS and Singapore approval with published blood-glucose safety data.

Kraut, kimchi and pickle makers rooted in decades- or centuries-old technique are scaling into mainstream retail — Walmart is betting big on fresh fermented foods with Cleveland Kitchen leading the charge, while Europe's largest sauerkraut factory reports surging global demand.

Industrial-scale vitamin manufacturing — B-group vitamins by direct fermentation, vitamin C by two-stage bioconversion of glucose, and vitamin D3 by UV photochemistry — concentrated overwhelmingly in China for bulk ascorbic acid while the EU retains unique fermentation capacity for riboflavin and stability-engineered feed premixes.

The microbial layer of winemaking — selected Saccharomyces wine yeasts, malolactic bacteria, microbial biocontrol tools and vineyard terroir-microbiome science that translate a vineyard's microbial identity (terroir) into controlled, expressive fermentation.
