Platform chemical biosynthesis

Arachidonic acid (20:4n-6), the omega-6 long-chain fatty acid of breast milk, produced by submerged fungal fermentation of *Mortierella alpina* and refined into oils and cold-water-soluble powders for infant formula — an industry concentrated in China (Cabio, Kingdomway, Hubei Fuxin) with DSM-Firmenich as the sole end-to-end Western supplier of life's®ARA.

Renewable routes to acrylic acid, the C3 monomer behind superabsorbent polymers, paints, coatings and adhesives, across two distinct value chains: bioethanol-derived bio-based acrylate esters already commercial at Arkema (Carling, France, bio-based ethyl acrylate at 40% bio carbon content since October 2024) and BASF (Ludwigshafen, portfolio switched to bio-based ethyl acrylate in August 2024), and direct fermentative acrylic-acid routes via 3-hydroxypropionic acid (Cargill's Issatchenkia orientalis SD108 platform) or direct yeast fermentation (Genomatica's Saccharomyces cerevisiae host at ~30 mg/L laboratory titre) still at pilot or research scale — no Chinese commercial originator confirmed as of 2026.

Enzymatic conversion of acrylonitrile to acrylamide via immobilized Rhodococcus rhodochrous cells, replacing copper-catalyzed synthesis for water-treatment, mining and papermaking flocculants.

Renewable routes to 1,3-butadiene, the C4 monomer behind synthetic rubber and ABS plastics, via two competing chemistries: catalytic bioethanol-to-butadiene conversion (Axens/Michelin/IFPEN's BioButterfly, ETB Global in the Netherlands) and methane gas fermentation (BioVerde Tech and Unibio in a 2026 partnership) — both still at demonstration or early-pilot scale, with no confirmed Chinese or Indian commercial originator as of 2026.

Producing the world's most ubiquitous petrochemical building block from renewable biomass and captured carbon.

Bio-based platform chemicals — succinic acid, itaconic acid, FDCA, and 1,4-BDO — produced via precision fermentation from C5/C6 sugars, replacing fossil feedstocks for biopolymers, plastics, and specialty chemicals; $5B market in 2025, growing >15% CAGR to 2030.

Industrial-scale fermentation of L-lactic acid, the upstream monomer feedstock for polylactic acid (PLA) bioplastics — fermentation scale-up, PLA-integrated value chains, and feedstock diversification: NatureWorks in the US, Corbion and Futerro in Europe, and Henan Jindan Lactic Acid in China.

Depolymerising the lignin fraction of woody biomass into renewable aromatic platform chemicals — vanillin, phenolics, BTX and lignosulfonate dispersants — replacing petrochemical aromatics.

Fermentation-derived terpenes and terpenoids — farnesene, limonene, valencene, squalane — replacing petrochemical and plant-extracted equivalents in cosmetics, flavors, fragrances and fuel additives as microbial mevalonate-pathway engineering scales.
