* By Lallemand Animal Nutrition
Evolving global aquaculture demand requires paradigm shift toward scientifically validated, preventive health solutions. Driven by a dedicated innovation ecosystem, Lallemand Animal Nutrition leverages its specialized library of over 12,500 marine microorganisms to deliver advanced solutions for gut microbiome management and mucosal immunity. This continuous cycle of cross-functional research translates deep-ocean biological assets into industrially reliable microbial products, securing long-term operational resilience and sustainable growth across intensive farming environments.
Beneath the surface of the world’s oceans lies a vast, largely untapped reservoir of microbial life, one that is increasingly shaping the future of aquaculture. At the heart of Lallemand’s field-led, marine-rooted microbial approach to aquaculture innovation is a distinctive biological asset. The Lallemand Marine Culture Collection (LMCC) is a living library of more than 12,500 marine microorganisms assembled over decades of sampling expeditions to some of the world’s most extreme and biologically rich marine environments. This collection is a key pillar of Lallemand’s aquaculture innovation strategy, complementing a broader range of non-veterinary microbial solutions derived from both marine and terrestrial sources. Notably, several strains from the LMCC are also used across other Lallemand business units beyond aquaculture, underscoring the collection’s value as a cross-functional scientific asset. Together, these capabilities position Lallemand as one of the most scientifically credible and forward-looking partners in the global aquaculture industry.
Reshaping Aquaculture Production
The urgent challenges confronting aquaculture producers today are well documented: rising production costs, tightening environmental, welfare and regulatory standards, mounting expectations for antibiotic-free production, and the persistent difficulty of maintaining animal health, water and soil quality across highly diverse production environments. Producers from Norwegian salmon fjords to Asian and Latin American shrimp and fish ponds are looking beyond conventional management approaches for biological solutions that are effective, consistent, and scalable. The question is: where will better solutions come from, and can the science behind them be trusted to deliver under real-farm conditions?
Meeting these expectations requires an approach to innovation that combines a genuine understanding of production realities with a differentiated biological knowledge base, and holds products to rigorous field- level validation before they reach the market. This is precisely the approach that defines Lallemand Animal Nutrition’s aquaculture strategy.
Innovation at Lallemand starts on the farm, where daily conversations with producers reveal the challenges that tomorrow’s solutions must solve.
The Marine-Origin Advantage
The LMCC is home to more than 12,500 strains of marine microorgan- isms — bacteria, yeasts, and molds — sourced from a wide range of habitats, including shallow coastal ecosystems, deep-sea sediments, and polar waters. Built over decades of targeted sampling expeditions, the collection represents one of the most extensive repositories of marine microbial diversity assembled for biotechnological application.
What makes marine-origin strains particularly valuable for aquaculture is precisely what shaped them: extreme and fluctuating salinity, variable temperature regimes, limited oxygen availability, and intense competition within complex aquatic microbial communities. These evolutionary pressures have equipped marine microorganisms with metabolic profiles that may offer distinct functional benefits from those of terrestrial-origin strains — properties that may confer distinct performance advantages in the aquatic environments where farmed species live.
This does not mean that all of Lallemand’s aquaculture solutions originate from the LMCC. Some well-established strains are of terrestrial origin with documented performance records. Terrestrial-origin strains remain important for some applications, while marine-origin strains broaden the functional toolbox for aquatic environments. The LMCC essentially serves as a complementary, strategically differentiated screening source that broadens the range of functional candidates available for development and opens biological avenues that terrestrial-only libraries cannot.
Field-Led Innovation: Starting Where It Matters Most
Unlike technology-push models that develop solutions in search of problems, Lallemand’s innovation cycle is largely demand-driven. A global team of aquaculture specialists — with expertise in both fish and shrimp production systems — operates across Europe, Asia, and Latin America, maintaining continuous engagement with farms, hatcheries and processing facilities. These specialists function as trained observers who translate operational pain points into precise scientific questions that directly shape R&D priorities.
This field intelligence is reinforced by Lallemand’s active participation in major international aquaculture congresses and technical forums, where the company engages with emerging scientific developments and evolving market needs. The result is an innovation roadmap continuously recalibrated to what producers actually require such as better support for gut microbiome, mucosal integrity or again animal resilience under environmental or management-related stress, reliable water and soil-quality maintenance, and microbial solutions that integrate seamlessly into existing farm management protocols. Every R&D project within Lallemand’s aquaculture portfolio traces back to a challenge identified in the field.
With over 12,500 strains collected from the world’s most demanding marine environments, the LMCC is not just a laboratory asset — it is a living atlas of microbial potential, built to anticipate the solutions that aquaculture will need tomorrow.
Scientific Rigor at Every Stage
Identifying a promising microbial strain is just the beginning. Every candidate — whether sourced from the LMCC or from terrestrial origins — is subjected to a rigorous, multistage evaluation protocol before it can advance toward product development. Functional potential criteria are defined according to the intended application: supporting gut microbiota balance, immune response, organic matter degradation, ammonia management, competitive exclusion of undesirable bacteria, or other targeted functions.
Alongside functional performance, candidates are screened for safety: absence of transmissible antibiotic resistance genes, absence of virulence factors, and demonstrated stability under the physical and chemical stresses of industrial fermentation and formulation. Industrial suitability and scalability — including the ability to survive and maintain activity during large-scale production and downstream processing — is evaluated in parallel, ensuring that only candidates with genuine commercial potential proceed.
The Oban facility in Scotland serves as the operational hub of the LMCC and a key scientific platform for this screening work. Operating at biosafety level 2 (P2 certification), the laboratory is equipped with High-Performance Liquid Chromatography (HPLC) for the identification and quantification of microbial metabolites, and a suite of bioassays configured for high throughput functional evaluation. The collection’s long-term integrity is maintained through rigorous preservation protocols: every strain is stored in triplicate using different preservation methods and physically separate locations, ensuring full traceability and resilience against loss.
Five Lallemand Centers of Excellence contribute specialized expertise spanning fundamental microbiology to applied nutrition science, supported by a global network of academic institutions, research centers, and specialist partners. This collaborative infrastructure accelerates discovery and provides independent scientific validation, while a dedicated internal R&D team translates findings into product development pathways.
In five years, Lallemand Animal Nutrition has conducted over 30 in vivo trials across multiple countries and species, ensuring that every product reaching the market has been validated under the conditions producers actually face.
From Controlled Conditions to Farm Performance
Scientific performance in controlled laboratory settings is merely a prerequisite. Lallemand’s commitment to evidence-based innovation is measured by the scope and rigor of its in vivo validation program. Two fulltime scientists are dedicated exclusively to aquaculture trial management, overseeing field and controlled experiments designed to evaluate support for gut and immune function, performance outcomes, stress resilience, and water quality management across diverse production contexts. In the field, more than 30 trials have been conducted in the past five years alone, on both fish and shrimp in multiple countries across wide- ranging production environments and factors like water temperatures, salinity regimes, biosecurity contexts, and management intensities. This geographic and biological breadth is deliberate. Having experienced the complexity of good animal health maintenance and microbial management for more than 40 years, we know that development of sustainable and efficient solutions requires a deep understanding of microbes as well as farm specificities. Only when robust results are demonstrated across varied real-world environments does a solution earn its place in Lallemand’s market-ready portfolio.
Lalsea Biorem and the LMCC in Action
Lalsea Biorem, Lallemand’s non-veterinary bioremediation solution for aquaculture pond management, offers the most concrete illustration of how the LMCC’s biological depth translates into practical, producer- level outcomes. Its development required systematic screening of thousands of LMCC strains against a demanding, specifically defined set of functional criteria.
Selected strains had to demonstrate robust microbial activity across a salinity range of 0 to 50 ppt — covering both freshwater and hypersaline production environments — and perform reliably under aerobic, anaerobic, and microaerobic conditions typical of oxygen-variable pond ecosystems. Functional screening targeted strains with broad enzymatic capacity to support degradation of the organic matter that accumulates in pond sediments, alongside demonstrated ammonium assimilation capacity to contribute to water quality management and reduce algal bloom risk. Overall microbial dynamics – including activity involving opportunistic microorganisms – were also evaluated as part of the screening framework for water quality management.
Each shortlisted candidate was validated under simulated farming conditions before the final product formulation was established. The result is a non-veterinary microbial solution with demonstrated effectiveness in both shrimp and fish ponds across multiple continents — a direct expression of both the LMCC’s unique biological diversity and the rigor of Lallemand’s end-to-end innovation and validation process.
Anticipating Tomorrow’s Challenges
What distinguishes the LMCC from a passive biological archive is the active, forward-looking scientific strategy that governs its use. Lallemand’s research agenda includes proactive screening of the collection against challenges that aquaculture is anticipated to face over the next years and decades such as the impact of non-conventional ingredients, of a warming world, of the application of One-health approach on animal and aquatic health, performance and microbial communities. Emerging production contexts — including recirculating aquaculture systems (RAS) and increasingly intensive pond management — also inform pre-emptive screening priorities. This anticipatory approach provides Lallemand with a structural advantage: when market needs crystallize around a new challenge, the company is ready. It draws on a collection that has been systematically characterized over decades, a scientific team already familiar with the most relevant candidates, and an industrial platform capable of scaling validated solutions in months rather than years. The LMCC is, therefore, not only a resource for today’s products — but also the strategic foundation of tomorrow’s innovation pipeline.
The ocean, long the source of life on Earth, is now becoming the source of solutions for aquaculture’s most pressing challenges — and Lallemand holds the key to that treasure.
