Biochemistry & industrial biotech
The industrial biotech sector: platform and specialty chemicals, polymers and materials, enzymes and biocatalysis.
The industrial sector is the bioeconomy’s most quantitative: every target molecule has a theoretical yield from sugar, and an honest page names that ceiling and shows where industry actually stands. Four clusters: platform chemicals — the monomers everything else stands on; specialty & fine chemicals — small volumes, high margins; polymers & materials — the same feedstock assembled into stuff; enzymes & biocatalysis — catalysts that make selectivity free and stability expensive.
The recurring motif is the titre–rate–yield trade: the organism is optimised for its own survival, not for your product, and engineering always buys one at another’s expense. The second motif is separation cost: more often than not it is not the fermentation but the recovery from a dilute broth that decides a product’s fate.
The entry point is platform chemicals: the carbon-ceiling logic runs through every molecule there.
- Platform chemicals Four monomers with four fates, lactic acid as the worked success case, and the by-product economics that set where a bio-route is viable.
- Specialty & fine chemicals Why the titre ceiling is usually set by the product itself, why a real mechanism fails at the delivery step, and when a claim is about feedstock.
- Polymers & materials Why bio-based and biodegradable are independent axes, why every enabling property carries its own failure mode, and how to design the exit.
- Enzymes & biocatalysis Kinetics and immobilisation, in-vitro polymer synthesis, catalysis on hydrocarbons and detergents — industrial enzymes from reactor to retail shelf.
