Research Lines
The “Aquatic Organisms Physiology and Applied Biotechnology” Research Group is made up of female researchers and fellows specialized in the study of aquatic resources and the development of innovative technologies applicable to the production sector. From the National University of Mar del Plata, we work on generating knowledge and solutions that promote the responsible and sustainable use of marine resources, in close collaboration with public and private sector stakeholders.
In recent years, the group has consolidated its track record in the areas of Marine Biotechnology and Aquaculture, addressing current challenges through a sustainable development approach. Our research lines are framed within principles of circular economy and natural resource sustainability, with a special focus on the valorization of fishery by-products and applied biotechnology.
Among the highlighted developments are:
- Study and characterization of enzymes obtained from fishery by-products
- Production of protein hydrolysates and obtaining bioactive peptides
- Development of microencapsulants for use as dietary additives in aquaculture or as functional agents in anti-fouling paints
- Improvement of vegetable meals through enzymatic hydrolysis to eliminate protease inhibitors
- Obtaining protein by-products from the bioconversion of fishing and aquaculture waste, through enzymatic processes or fermentations with brewer's yeasts.
Our projects are developed in collaboration with fishing sector companies and public organizations, with the common goal of adding value to filleting waste and advancing toward zero-waste production schemes. From the Research Group, we work on developing technologies that transform these discards into high-value inputs, with applications in various areas of interest.
Currently, promising results are being obtained in the characterization of functional compounds derived mainly from shrimp heads (Pleoticus muelleri). Unlike the common use of the exoskeleton for chitin/chitosan extraction, our research focuses on valorizing the soft parts, which allows for a double benefit from these wastes. We have verified that the enzymatic extracts obtained from residues of this species exhibit proteolytic activity and are stable under various physicochemical conditions relevant to industry.
Additionally, we are exploring the potential of viscera and non-edible tissues from various marine species (hake, alfonsino, ling, silverside) and aquaculture species (pacú and tilapia) as alternative sources of functional compounds.
We have the technical capacity, infrastructure, and experience necessary to address joint challenges with the production sector, oriented toward innovation, resource optimization, and the generation of new products from fishery by-products.
