Industrial enzymes: Production route
One fermentation method, many enzyme families
What this tab covers How it is made: the main production routes or, for product families, the main product types and technologies, compared on share of supply, inputs per tonne, plant scale, yield, co-products and unit cost.Enzymes are made by fermentation of engineered microbes and sold by activity. The family is best split by enzyme class: carbohydrases (amylases, glucoamylases, cellulases, xylanases), proteases, lipases, phytases and nucleic acid enzymes (polymerases and nucleases). Production technology is shared; what differs is the strain, the substrate and the formulation. Western leaders use submerged fermentation at large scale; Indian and Chinese makers also use solid-state fermentation for some products (indicative).
Routes compared
| Route | Share of supply | Inputs per tonne | Typical scale | Yield | Co-products | Unit cost |
|---|---|---|---|---|---|---|
| Carbohydrases (amylases, glucoamylases, cellulases, xylanases) | the largest enzyme class (indicative) | glucose or starch plus nitrogen; quantities not published | large fermentation sites (Denmark, US, China, Brazil, India) (indicative) | not published | spent biomass to fertiliser or biogas (indicative) | not published |
| Proteases | second-largest class (indicative) | not published | large-scale | not published | biomass | not published |
| Lipases and specialty food enzymes | smaller (indicative) | not published | medium-scale | not published | biomass | not published |
| Phytases and feed enzymes | most feed enzyme value (indicative) | not published | large-scale | not published | biomass | not published |
| Polymerases, nucleases and diagnostics | small volume, high value | not published | small batch | not published | not material | not published |
How each route works
Carbohydrases (amylases, glucoamylases, cellulases, xylanases)Bacillus and Aspergillus amylases liquefy and saccharify starch for ethanol, syrups and brewing; Trichoderma cellulases break down biomass and finish textiles.
Core of ethanol and food markets.
Grand View and MarketsandMarkets type lists; indicative ProteasesBacillus subtilisins for detergents; other proteases for food, leather and feed.
Detergent workhorse; allergy risk in dust form.
indicative Lipases and specialty food enzymesFungal lipases for detergents, baking, oils and dairy; lactases, transglutaminase and others for food.
High value; many niche products.
indicative Phytases and feed enzymesEngineered E. coli-derived phytases expressed in fungi or yeast, coated to survive feed pelleting.
Proven payback through phosphate savings.
indicative Polymerases, nucleases and diagnosticsHigh-purity enzymes for PCR, sequencing and molecular biology.
Very high price per gram.
