Why is SeaGraze® 12x as potent as competing products?
At Symbrosia, we are committed to pioneering solutions that push the boundaries of sustainable aquaculture and methane reduction. With years of dedicated research and development, we have built a strong foundation of technological advancements that are not only redefining seaweed cultivation but also expanding its potential in multiple industries. Today, we’re excited to launch a blog series that dives deeper into our latest breakthroughs, spanning production innovations, automation, biorefinery applications, and precision breeding. Stay tuned as we explore these advancements and their impact on the future of sustainable aquaculture.
One of our core missions at Symbrosia is to get as many cows as possible on our methane-reducing feed—efficiently, sustainably, and at scale. Achieving this starts from something nearly microscopic: a single Asparagopsis taxiformis sporophyte puff, weighing less than a gram. Responsibly sourced from the wild, this tiny fragment is the foundation of our cultivation process, ensuring minimal impact on natural populations. Over 4.5 months, our refined inoculum chain propagates this puff into nearly 2 million times its starting weight—a feat made possible by six years of relentless research and innovation. With industry-leading bromoform concentrations in our product, we maximize methane reduction per kilogram, enabling greater climate impact while driving higher revenue efficiency and cost-effectiveness at scale.
Scaling seaweed cultivation at this level was no easy task. Through rigorous testing, we developed the Flexible Cell Formation Model™, a meticulously designed production flow that prioritizes bioactive concentration, yield optimization, and scalability. This staged approach integrates batch and continual harvest systems to support the evolving needs of A. taxiformis, balancing sterility, nutrient availability, and light exposure at each phase. Culturing conditions are meticulously managed to enable 1:1 transfers into larger vessels, minimizing labor demands while maximizing land use efficiency and reducing reliance on biomass from the indoor lab.
High bromoform concentrations have been established in our scaled open pond systems.
Early-stage cultures thrive in controlled conditions, where artificial lighting ensures consistent intensity, nutrient levels are carefully regulated in a closed system, and strict sterility is maintained. As the cultures gain momentum, we transition biomass outdoors where ocean-sourced nutrients, natural temperature regulation, and solar energy drive further growth. This seamless integration of indoor and outdoor phases reduces labor demands, optimizes production efficiency, and maximizes bromoform yield—the key compound responsible for methane reduction in cattle.
Through continuous optimization of our culturing parameters, we’ve increased bromoform content by 167% in final-stage biomass in 2024 alone. This steady, incremental enrichment of bromoform validates the feasibility of large-scale Asparagopsis cultivation, ensuring we can meet the rising demand for methane-reducing livestock feed additives. Our 50 kL cultivation tanks now serve as the final production stage—a critical milestone for scaling up. With our modular and expandable system, we can readily increase production capacity to the acreage level, accelerating our ability to bring climate-positive solutions to ranchers worldwide.
Extensive research has resulted in a steady increase of bromoform concentrations, surpassing technical KPI's and published literature.
With a single 50,000L tank, Symbrosia can feed 7,500 cows—an unmatched level of efficiency in the Asparagopsis production space. For comparison, direct competitors can support only about 1/12th of that number with the same final-stage growing volume. Our streamlined cultivation process enables us to achieve significant methane reductions with far less infrastructure.
Looking ahead, we are refining culture parameters to optimize feed output per hectare, further improving efficiency and scalability. The Flexible Cell Formation Model™—the culmination of our years of R&D—ensures that our seaweed-based solution is not only effective but also practical for mass adoption. By leveraging our proven production flow and semi-continuous harvesting, we are reducing labor intensity while maintaining high yields, setting the stage for a future where sustainable, methane-reducing livestock feed is the norm.
At Symbrosia, we believe that tackling climate change starts at the source—and for us, that means harnessing the power of the ocean to revolutionize agriculture.
