How do microalgae enhance cellular meat production?

Question

Accepted Answer

Microalgae Offer a Cheaper, More Ethical Alternative in Cellular Meat Production

A Czech Republic-based startup, The Mewery, is pioneering the use of microalgae to reduce the cost and address ethical concerns associated with cellular meat production. This innovative approach involves combining animal cells with microalgae cells, thereby eliminating the need for foetal bovine serum (FBS), a traditional component that has raised ethical questions and contributed to high production costs. The Mewery's method aims to create a more economically viable and ethically sound cellular meat product, with plans to introduce its algae-based meat to restaurants by 2025, contingent on European Union authorisation.
The Role of Foetal Bovine Serum in Cellular Agriculture

Historically, the production of cellular meat, also referred to as lab-grown or in-vitro meat, has relied on foetal bovine serum. This substance is derived from the blood of foetuses removed from slaughtered cows during the process of dairy production. FBS serves a critical function in providing the necessary growth factors that stimulate animal cells to multiply and develop into muscle fibres. However, the reliance on FBS presents significant challenges, including its substantial cost, which impacts the overall economic feasibility of cellular meat, and ethical considerations regarding animal welfare and the sourcing of the serum.
Microalgae as a Substitute for Growth Factors

The Mewery's innovation lies in its utilization of microalgae to replicate the growth-promoting functions previously fulfilled by FBS. By cultivating specific types of microalgae, the company has developed a method to extract the necessary components that support cell multiplication and muscle fibre development. This process allows for the creation of cellular meat without the ethical baggage and high expense associated with FBS. The Mewery's proprietary blend reportedly consists of 75% animal cells and 25% cells derived from microalgae, a composition that significantly alters the production paradigm.
Economic and Ethical Advantages of Algae-Based Cellular Meat

The integration of microalgae into cellular meat production offers compelling economic and ethical advantages. Economically, it presents a pathway to significantly reduce manufacturing costs by bypassing the expensive procurement of FBS. This cost reduction is crucial for making cellular meat competitive with conventionally produced meat. Ethically, it eliminates the direct use of animal-derived products like FBS, addressing concerns about animal welfare that are often raised in discussions about cellular agriculture. The Mewery's ambition to produce products such as sausages, meatballs, minced meat, and pork tenderloin using this method underscores the potential for a more sustainable and widely accepted future for cellular meat.
