LIVING MARINE RESOURCES
Preventing illegal seafood trade using machine-learning assisted microbiome analysis
This study uses microbiome profiling and machine-learning to trace the origin of Manila clams, targeting the illegal seafood trade. DNA from clams collected across sites and seasons was analyzed, with ML achieving high accuracy (Cohen K-score > 0.95) in distinguishing clams from banned and farming areas. The method is robust against seasonal changes and ready for practical use in seafood traceability.

Optimizing a biorefinery design for the valorization of Rugulopteryx okamurae by to extracting bioactive compounds and enhancing boost methane production from Rugulopteryx okamurae
This investigation examines the invasive macroalga Rugulopteryx okamurae in the Mediterranean Sea for biorefinery applications. Ethanol extraction yields more polyphenols, while water extraction is better for reducing sugars. Sequential extraction methods enhance valuable compound yields by 30-80%. The physicochemical properties of liquid extracts reveal significant differences in antioxidant activity and concentrations of high-value compounds. Additionally, methane production potential from the extracted residue indicates effective anaerobic digestion.

MARINE BIOTECHNOLOGY
Fermented Fish Collagen Attenuates Melanogenesis via Decreasing UV-induced oxidative Stress
In this study was evaluated the effect of fermented collagen (FC) on decreasing melanogenesis via decreasing oxidative stress. The results demonstrated that FC treatment increased levels of glycine receptors and transporters in UV-irradiated keratinocytes and decreased oxidative stress markers as well as altered protein expressions related to melanogenesis in melanocytes. In conclusion, the study highlights the potential of FC as a cosmetic agent to combat UV-induced hyperpigmentation problems.

Antioxidant Marine Hydrolysates Isolated from Tuna Mixed Byproducts: An Example of Fishery Side Streams Upcycling
This research focuses on extracting bioactive peptides from tuna mixed byproducts, aiming to upcycle fishery side streams into valuable products. Two extraction methods were tested: one with an exogenous enzyme (Enzymatic-Assisted Extraction) and one without, yielding similar amounts of protein hydrolysates. The enzymatic method produced smaller peptides (1.3 kDa) compared to the non-enzymatic method (2.2 kDa), with the former showing better antioxidant activity. Both types of hydrolysates demonstrated potential health benefits, including antihypertensive and anti-osteoporotic effects, but no anti-inflammatory properties were found.

DNA vaccine for fish against salmonid alphavirus
Salmonid alphavirus (SAV) is a key pathogen in salmonid aquaculture. DNA plasmid vaccines expressing SAV antigens exist but are hard to produce at scale and require high doses, making them costly. This invention introduces an improved plasmid for DNA vaccines against SAV, requiring significantly less DNA per dose. The plasmid includes a gene encoding the bacterial enzyme Fab.
