Food microorganisms (starter cultures)

01Overview and value chain

Markers: [EC: EU food enzyme/microorganism authorization framework | OECD: Food systems | Regulator: FDA (USA), EFSA (EU)]

Food microorganisms as starter cultures are the live bacteria, yeast and mold strains dosed into milk, dough or must to kickstart a specific, repeatable fermentation — the biological input every downstream fermented product in this catalog ultimately depends on. Novonesis closed the first quarter of 2026 with revenue of €1.119 billion and overall growth of 7%, with dairy cheese cultures performing particularly strongly across both mature and emerging markets, and is deepening its India dairy focus through a “Next Level Dairy” biosolutions push. IFF launched a transformational cheese culture in mid-2025 that cuts water use in semi-hard cheese production, and its Choozit Lift culture eliminates 100% of curd-washing water — addressing cheesemakers’ sustainability and energy-cost pressures directly through the microorganism itself rather than downstream process changes. Sacco System, describing itself as a “microbial innovator,” supplies starter cultures spanning dairy, meat and fish fermentation. In China, Angel Yeast operates an 8,500-ton specialty yeast facility alongside a new brewing microbial pilot platform, while in India the National Dairy Development Board has begun supplying indigenous starter cultures directly to major cooperatives Amul, Banas and Mother Dairy.

Key directions of food microorganism starter cultures:

1. Water/energy-efficient cheese cultures (Water/Energy-Efficient Cheese Cultures): engineered cultures that cut water or energy consumption in cheese production directly through the microorganism’s metabolic behavior.
2. Multi-format starter portfolios (Multi-Format Starter Portfolios): a single supplier’s culture range spanning dairy, meat, fish and other fermented-food categories.
3. National dairy-sovereignty starter supply (National Dairy- Sovereignty Starter Supply): government or cooperative-backed indigenous starter-culture production reducing reliance on imported cultures for a country’s dairy cooperatives.
4. Industrial-scale specialty yeast production (Industrial-Scale Specialty Yeast Production): dedicated large-volume yeast facilities supplying both established and newly piloted fermentation applications.

Value chain levels

Cross-cutting technologies of the sector:

• Metabolically engineered water-saving cultures (Metabolically Engineered Water-Saving Cultures): cultures selected or engineered to reduce curd-washing or other process water use directly.
• Multi-category culture banking (Multi-Category Culture Banking): strain libraries maintained across dairy, meat, fish and beverage fermentation categories under one supplier.
• Freeze-dried lactic culture stabilization (Freeze-Dried Lactic Culture Stabilization): lyophilization technology preserving live lactic culture viability through storage and distribution.

02US

The US hosts a major flavor-and-bioscience group whose new dairy cultures target sustainability metrics directly through microbial engineering.

water-saving cheese cultures, low-alcohol brewing enzymes, industrial and specialty cheese culture ranges

• IFF: launched a transformational culture in mid-2025 that improves energy and water efficiency in semi-hard cheese production, and its CHOOZIT Lift culture eliminates 100% of curd-washing water use; its CHOOZIT cheese culture range serves both high-volume industrial and specialty cheesemakers, alongside a Diazyme Nolo enzyme enabling full-flavored no- and low-alcohol beer.

03CN

China hosts a large-scale specialty yeast producer expanding into new fermentation applications alongside its established production base.

8,500-ton specialty yeast facility, new brewing microbial pilot platform, traditional starter diversity research

• Angel Yeast: operates an 8,500-ton specialty yeast production facility and has launched a new brewing microbial pilot platform to extend beyond its established yeast production base.
• Traditional starter research: academic research on the microbial diversity of traditional Chinese starters and screening for special functional strains is active, reflecting continued scientific interest in the country’s traditional fermentation microorganism base.

04EU

Denmark and Italy anchor the region’s activity, spanning the world’s largest dedicated biosolutions group and a diversified multi-format starter-culture specialist.

cheese-culture-led revenue growth, India dairy biosolutions push, multi-format starter innovation

• Novonesis: closed Q1 2026 with revenue of €1.119 billion and 7% overall growth, with dairy cheese cultures performing particularly strongly, and is deepening its India dairy focus through a “Next Level Dairy” biosolutions push alongside its Bovacillus dairy-cattle probiotic.
• Sacco System: an Italian “microbial innovator” supplying starter live cultures across dairy, meat and fish fermentation, including its PerforMilk platform aimed at preserving milk protein quality through the dairy production process.

05Leading companies and research institutes

06Tech stack and innovations

The stack turns strain selection into a repeatable, shelf-stable production input for downstream fermentation.

1. Water-saving culture engineering (Water-Saving Culture Engineering):
   • cultures are selected or engineered to reduce process water use (curd-washing) directly through their metabolic behavior rather than a separate process fix.
   • case: IFF’s Choozit Lift eliminates 100% of curd-washing water use in the cheeses it is formulated for.
2. Multi-category strain banking (Multi-Category Strain Banking):
   • a single supplier maintains strain libraries spanning multiple fermented-food categories rather than specializing in one.
   • case: Sacco System supplies starter live cultures across dairy, meat and fish fermentation from one microbial innovation platform.
3. National indigenous culture supply (National Indigenous Culture Supply):
   • a government or cooperative body develops and supplies its own starter cultures to reduce dependence on imported strains.
   • case: NDDB has begun supplying indigenous starter cultures directly to Amul, Banas and Mother Dairy, India’s largest dairy cooperatives.

Stage 1: Strain isolation/banking

A candidate bacterial, yeast or mold strain is isolated from a traditional or environmental source and banked.

Stage 2: Fermentation scale-up

The strain is fermented at increasing scale to produce industrial biomass volume.

Stage 3: Freeze-drying/stabilization

The biomass is freeze-dried or otherwise stabilized into a shelf-stable culture format.

Stage 4: Culture formulation

The stabilized culture is formulated — alone or blended with other strains — for a specific target application (cheese, bread, beer, cured meat).

Stage 5: Food-microorganism authorization

The formulated starter culture clears FDA or EU regulatory review before commercial sale.

Stage 6: Downstream fermentation

The producer doses the authorized culture into milk, dough or must, kickstarting the specific fermentation that every downstream fermented-food article in this catalog ultimately depends on.
