LIVE MARINE RESOURCES

Preventing illegal trade in seafood products using machine-learning-assisted microbiome analysis

This study uses microbiome profiling (MP) and machine learning (ML) to trace the origin of Manila clams, with the aim of combating illegal trade in seafood products. The DNA of clams collected from different locations and seasons was analyzed, with ML achieving high accuracy (Cohen K-score > 0.95) in distinguishing clams from prohibited and cultivation areas; it highlights that the present method is robust and ready for practical use in the traceability of seafood products.

Optimization of biorefinery design to extract bioactive compounds and increase methane production from Rugulopteryx okamurae

This research examines the invasive macroalgae Rugulopteryx okamurae in the Mediterranean Sea for biorefinery applications, which is a promising alternative within a circular economy model. The objective is to evaluate the potential of Rugulopteryx okamurae as a raw material for the extraction of reducing sugars (RS) and total polyphenolic compounds (TPC) with antioxidant capacity, followed by the production of methane as fertilizer. As a result, the biochemical methane potential of the extracted solid residues increased as the RS and TPC content was reduced (120–150 NLCH4 Kg−1VS) and meets European standards for organic fertilizers, allowing it to be used directly.

MARINE BIOTECHNOLOGY

Fermented fish collagen attenuates melanogenesis by reducing UV-induced oxidative stress

This study evaluated the effect of fermented fish collagen (FFC) on reducing melanogenesis by reducing oxidative stress. The results showed that treatment with FC increased the levels of glycine receptors and transporters in UV-irradiated keratinocytes and decreased oxidative stress markers, as well as altering 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 mixed tuna by-products: an example of secondary fisheries streams

This research focuses on the extraction of bioactive peptides from mixed tuna by-products, aiming at their economic valorization. Two methods of enzyme-assisted extraction (EAE) were tested: one with enzyme and one without, resulting in similar amounts of protein hydrolysates. The enzymatic method (enzymatic hydrolysates – EH) produced smaller peptides (1.3 kDa) compared to the non-enzymatic method (non-enzymatic hydrolysates – NEH) (2.2 kDa). At the same time, several biological analyses were performed, verifying that HE presented a more promising antioxidant activity, which could be exploited in various sectors such as nutrition, biomaterials, and cosmetics.

DNA vaccine for fish against salmonid alphavirus

Salmonid alphavirus (SAV) is a key pathogen in salmonid fish aquaculture. There are plasmid DNA vaccines that express SAV antigens, but they are difficult to produce on a large scale and require high doses, making them expensive. This invention introduces an improved plasmid for DNA vaccines against SAV, which requires significantly less DNA per dose. The plasmid includes a gene that encodes the bacterial enzyme Fab.
