Single-cell proteins (SCP), derived from microorganisms such as algae, yeast, fungi, and bacteria, are gaining increasing recognition as alternative protein sources for food and animal feed. One of the key advantages of SCP is its ability to produce large quantities of high-protein biomass in a relatively short time using fewer natural resources. This efficiency makes SCP an attractive option, particularly considering the rising demand for sustainable nutrition.
The use of microbes and microalgae as food and feed ingredients with high protein content is gaining renewed scientific and commercial interest. Additionally, the rising cost of traditional protein sources and the continuous growth in global protein consumption are prompting manufacturers to explore SCP as a cost-effective alternative. Its nutritional richness and scalable production make it a promising substitute, especially in the animal feed sector.

Single-cell protein involves less energy and feedstock consumption during production, which reduces the carbon footprint significantly, and also reduces stress over the environment, making it a sustainable protein feed source over other conventional protein sources. Growing consumer awareness about climate change and sustainability has led to increasing demand for eco-friendly food sources.
A 2023 survey by the International Food Information Council (IFIC) revealed that 65% of consumers are more likely to purchase products with sustainability claims. In response, food manufacturers are increasingly investing in low-impact protein solutions such as SCP. Manufacturers are constantly innovating ways for sourcing raw materials as well as producing products in the most sustainable ways to attract more customers. Single-cell protein contributes to the safety of the environment by using less resources and reducing the carbon footprint. These factors are expected to drive product sales in the coming years.
The single-cell protein market faces significant challenges due to intense competition from well-established conventional protein sources such as soy, whey, and fishmeal. These traditional proteins have long-standing supply chains, proven nutritional profiles, and widespread consumer acceptance, making it difficult to displace in both food and feed applications.
Additionally, conventional proteins often benefit from economies of scale, leading to lower production costs and more competitive pricing compared to SCP products. Consumer skepticism about the novelty and safety of SCP, along with limited regulatory frameworks in some regions, further hampers adoption. As a result, despite its sustainability and nutritional benefits, SCP struggles to achieve large-scale market penetration. To overcome this, producers must focus on educating consumers, improving cost-efficiency, and forming strategic partnerships to build trust and broaden SCP’s application across industries.
The integration of single-cell protein into animal feed presents a major opportunity for market growth. SCP offers a rich source of high-quality protein, essential amino acids, and other nutrients, making it a strong alternative to traditional feed components such as soybean meals and fishmeal. Unlike conventional protein sources, SCP can be produced rapidly and sustainably using limited land, water, and agricultural inputs. This makes it particularly valuable as the global livestock and aquaculture industries face increasing pressure to meet rising protein demand while minimizing environmental impact.
Additionally, SCP production can utilize waste streams from agriculture or industry, supporting a circular economy. Its consistent quality and scalable production potential further enhance its appeal. As producers seek cost-effective, nutritious, and eco-friendly feed options, the adoption of SCP in animal feed formulations is expected to accelerate, creating new growth avenues in the global protein market.
Algae-based single-cell proteins lead the market due to their high protein content, rapid growth, and low resource requirements. Cultivable in open ponds or bioreactors, algae are cost-effective and eco-friendly, utilizing sunlight and CO for sustainable production. Commonly used algal species include Spirulina (SPA), Chlorella pyrenoidosa, and Chondrus crispus, which are rich in amino acids, vitamins, and antioxidants. These are widely used in animal feed and gaining traction in human nutrition and nutraceuticals.
Yeast, such as Saccharomyces cerevisiae, Candida tropicalis, and Candida utilis is valued for its high protein yield and digestibility, especially in animal feed and pet food formulations. Fungi, including strains like Aspergillus fumigatus, Aspergillus niger, and Rhizopus cyclopean, thrive on organic waste, making them a cost-effective and sustainable protein source. They are particularly suited for use in meat alternatives due to their fiber and B-vitamin content. Bacteria offer rapid production and substrate flexibility. Notable species include Pseudomonas fluorescens, Lactobacillus, and Bacillus megaterium, which are primarily used in aquafeed and livestock nutrition due to their scalability and efficiency.
