Key research themes

1. How can cellular agriculture and engineering biology revolutionize sustainable seafood production?

This research theme investigates the innovative approach of producing seafood through cell and tissue cultures of marine organisms, a method known as cellular agriculture. It aims to address public health, environmental, and animal welfare challenges associated with conventional marine capture and industrial aquaculture. By integrating advances in biomedical engineering, genetic modification, and closed-system aquaculture, this area explores scalable, controlled, and ethical seafood production alternatives that may mitigate overfishing and environmental impacts.

Key finding: Rubio et al. (2018) demonstrate that cellular agriculture can be extended to marine species, specifically fish, proposing cultured muscle tissue production as a solution to challenges such as overfishing, pathogen spread, and... Read more

2. What roles do marine microorganisms and their metabolites play in advancing industrial, pharmaceutical, and environmental biotechnologies?

This theme centers on the bioprospecting and utilization of the vast diversity of marine microorganisms—bacteria, fungi, archaea—and their bioactive metabolites. The research explores microbial genetic and functional diversity as a reservoir for novel biocatalysts, secondary metabolites, and bioactive compounds with applications spanning industrial production, pharmaceuticals, agriculture, cosmetics, and environmental remediation. It emphasizes methodological advances such as metagenomics and culture techniques to overcome challenges posed by unculturable microbes, and highlights microbial consortia and microbiome engineering in algal biotechnology for improved commercial viability.

Key finding: This review articulates that marine microorganisms represent an almost inexhaustible resource of genetic and functional diversity due to their adaptive evolution, making them prime targets for biotechnological exploitation.... Read more

3. How do marine macroorganisms and algae contribute to the discovery of biomolecules and biomaterials for pharmaceutical, nutraceutical, and biotechnological applications?

This research area focuses on exploiting marine macroorganisms, including seaweeds, sponges, corals, and other invertebrates, as sources of secondary metabolites, enzymes, biopolymers, and bioactive compounds with broad applications. It addresses the characterization, sustainable harvesting, cultivation, and biotechnological processing of biomass to develop new pharmaceuticals, nutraceuticals, cosmeceuticals, and environmentally friendly biomaterials. The theme further examines the integration of omics and cultivation technologies to unlock the commercial and environmental potential of these marine resources.

4. What frameworks and strategies enhance sustainable growth and governance in marine (blue) biotechnology sectors?

This theme examines the policy, legal, and biosecurity dimensions integral to the responsible development of marine biotechnology. It investigates regulatory instruments such as the Nagoya Protocol, international ocean governance (e.g., UNCLOS, BBNJ Agreement), intellectual property rights, and Responsible Research and Innovation (RRI) frameworks. Additionally, it encompasses biosecurity challenges in aquaculture and seaweed farming, aiming to balance innovation, environmental protection, and equitable benefit-sharing while mitigating risks such as disease outbreaks and invasive species dissemination.

Key finding: This study highlights significant gaps in awareness and implementation of European and international regulations including the Nagoya Protocol within the marine biotechnology community. It stresses that insufficient... Read more
