Bacterial Proteins
Produced from single-cell bacteria. Mostly used in industrial and feed applications.
Common uses:
• Animal feed supplements (e.g., methanotrophic bacteria)
• Industrial enzyme production
• Biotechnology processesKey traits: Very fast growth, high yield, but mainly non-food applications today.
Microbial Fungal Proteins — Mycoprotein
Made from filamentous fungi and developed specifically for human food.
Examples: FuNext Mycoprotein, Quorn (Fusarium venenatum)
Nutritional features:
• 40–45% protein
• Complete amino acid profile
Functional features:
• Naturally meat-like fibrous texture
• Versatile in cooking
Applications: Meat alternatives, ready meals, snacks, beverages, and food ingredients
Key traits: High-quality protein, excellent texture, sustainable and scalable production.
Algal Proteins
Derived from photosynthetic microalgae.
Examples:
• Spirulina — contains phycocyanin, known for antioxidant properties
• Chlorella — 50–60% protein, widely used in supplementsKey traits: Produced through photosynthesis, high protein density, rich in micronutrients.
