In a groundbreaking initiative to revolutionize sustainable protein production and combat climate change, the Technical University of Denmark’s (DTU) biotechnology research institute, BRIGHT, has joined forces with Novonesis, a leader in biosolutions, to engineer and evolve microbes capable of converting waste carbon dioxide (CO₂) into nutritious, sustainable protein at industrial scale. This collaboration represents a significant leap forward in the pursuit of carbon-neutral bioeconomy solutions with enormous potential to reshape the future of food production.
Launched in 2023, this ambitious endeavor is orchestrated under the framework of The Acetate Consortium—a global collaboration fueled by generous funding from the Gates Foundation and the Novo Nordisk Foundation. The consortium combines the expertise of industry leaders such as Novonesis and Topsoe with top-tier academic institutions, including Aarhus University, the University of Copenhagen, and Northwestern University. Their shared goal is to engineer microbial processes that convert captured CO₂ into high-value protein ingredients, reducing reliance on terrestrial farming and drastically lowering the environmental footprint of protein production.
At the heart of this scientific challenge is acetate, a simple but tough substrate derived from captured carbon. While microbes naturally flourish on glucose from traditional agricultural sources, most strains are ill-equipped to efficiently metabolize acetate. Overcoming this bottleneck is critical to unlocking a scalable, carbon-neutral protein production pipeline. BRIGHT, renowned for its cutting-edge Biofoundry—an automated, high-throughput microbial evolution platform—aims to pioneer the next generation of engineered yeasts and fungi optimized for acetate-based fermentation.
This endeavor harnesses evolutionary engineering, a sophisticated technique where microbes are subjected to selective pressures over multiple generations to evolve traits desirable for industrial biotechnology. By accelerating natural selection in a highly controlled, automated environment, BRIGHT’s researchers can systematically enhance microbial acetate tolerance, uptake rates, and protein productivity at a pace unreachable through conventional strain development methods. This approach turns evolution into a precise design tool rather than a slow, random process.
Professor Adam Feist, the project lead at BRIGHT, explains, “We are not merely testing if microbes can survive on low-carbon inputs; we are evolving them to thrive—growing faster, consuming acetate more efficiently, and generating higher protein yields in ways that meet industrial scale demands.” This philosophy underscores the transformative power of combining synthetic biology with evolutionary strategies, offering a scalable blueprint for sustainable food production that transcends traditional agricultural constraints.
Novonesis brings decades of expertise in strain design and bioprocess optimization, complementing BRIGHT’s pioneering microbial evolution capabilities. Claus Crone Fuglsang, Novonesis’ Chief Scientific Officer, emphasizes the strategic synergy: “Our partnership with BRIGHT enables us to accelerate the development of yeasts and fungi tailored to convert acetate into protein rapidly and cost-effectively. This collaboration advances us closer to a reality where CO₂-based proteins become integral to global food systems.”
The overarching vision is a circular bioeconomy where waste carbon emissions are captured and reincorporated into the production of nutritious food, reducing environmental impact while increasing economic value. Such a system diminishes dependence on farmland—a resource increasingly pressured by climate change and demographic growth—while also shrinking the greenhouse gas footprint tied to traditional protein sources like meat and soy.
The project benefits from BRIGHT’s sophisticated automated evolution platform, enabling continuous culture and real-time monitoring of microbial populations adapting to acetate-rich environments. This technology exponentially reduces the time required for strain improvement, compressing what once took years of trial and error into months or weeks. The platform’s integration of genomic, metabolic, and physiological data guides iterative evolution, ensuring targeted, rational enhancements.
BRIGHT itself stands at the forefront of global biotechnology innovation, recognized among the top five universities worldwide for its impact in the field. Founded with a mission to expedite the green transition, BRIGHT brings together academia, industry, and government stakeholders to develop groundbreaking solutions across sustainable materials, microbial foods, and net-zero agriculture. Their focus remains on creating biotech processes that are scalable, economically viable, and ecologically sound.
Meanwhile, Novonesis exemplifies the rising influence of biosolutions across diverse industries, employing microbiology-driven technologies to reinvent how products are made, consumed, and experienced. With a workforce of over 10,000 specialists, the company integrates scientific rigor with market insights, propelling biological innovation that benefits both customers and the planet.
Together, through The Acetate Consortium, these partners leverage their combined strengths to tackle one of the largest challenges of our time—carbon capture and utilization for sustainable nutrition. The consortium’s inclusive composition, spanning universities, private companies, and research centers, fosters multidisciplinary innovation that is crucial to navigating the complexities of microbial engineering at scale.
Professor Jochen Förster, Director of the BRIGHT Biofoundry, highlights the collaboration’s significance: “Our joint venture embodies what successful impact-driven research requires—aligned goals, complementing expertise, and the determination to embrace complexity. We anticipate expanding and deepening this partnership in the years ahead to deliver tangible solutions for global sustainability.”
This pioneering work represents far more than a scientific milestone—it lays the foundation for a new paradigm in how humanity addresses food security and environmental stewardship simultaneously. By rerouting waste CO₂ emissions into the creation of sustainable proteins through evolved microbial factories, this initiative promises to revolutionize food manufacturing while mitigating climate change.
As the world searches for viable paths to a net-zero future, the intersection of synthetic biology, automated evolution, and industrial biotechnology showcased by BRIGHT and Novonesis offers a compelling vision. Their collaboration not only advances fundamental understanding of microbial metabolism but also delivers potent tools for industrial translation, ramping up production efficiency, lowering costs, and ensuring that food innovation keeps pace with ecological imperatives.
In essence, these efforts highlight that the future of food is not constrained by the limits of traditional agriculture but empowered by the transformative potential of engineered biology. With continued investment, research, and partnership, CO₂-derived protein could emerge as a cornerstone of the circular bioeconomy—feeding populations sustainably while restoring the balance between human industry and the planet’s ecosystems.
