• Patent | Method for the identification of antimicrobial polypeptides in Mytilus edulis

    Authors: María del Mar Costa Portela, Beatriz Novoa García, Antonio Figueras Huerta, Sonia Dios Vidal, Camino Gestal Mateo

    The invention provides a method for the identification of polynucleotides, coding precursors of polypeptides, with antibacterial and antiviral activity (myticines and mytilines). More detailed information can be obtained here.

  • Patent | Procedure to prevent fish rankness and quality loss in fresh and processed products

    Authors: Isabel Medina; Jose manuel Gallardo Abuin; Ana Alonso Pérez; Manuel Pazos Palmeiro; Juan Fernandez Bolaños Guzman; Isabel Sanchez Alonso

    Prevention of fish rankness and quality loss consists in reducing susceptibility to oxidation through the production of an oxygen barrier by glazing and the addition of hydroxythyrosol as a natural water-soluble antioxidant. The technique is also applicable to fish and crustacean products. More detailed information can be found here.

     

     

  • Patent | Modified atmospheres for conservation of live bivalves in hermetic packaging

    Authors: Laura Pastoriza; Gabriel Sampedro Cedeira; Marta Bernárdez Costas; Marta López Cabo; Juan José Rodríguez Herrera

    The invention relates to a method of preserving live shellfish using a modified atmosphere that is rich in oxygen and contains a second main nitrogen component, so as to preserve live bivalve shellfish and safeguard their quality for as long as possible throughout the whole marketing and sale process. The commercial shellfish packaging must be full and well compacted, for which purpose units must be perfectly inserted during the filling operation using a vibrator so that bivalve shellfish cannot open their valves, thus losing intervalvar liquid, throughout the marketing process. The invention relates to the most popular bivalve on the market in terms of sales and price and, as a result, is of particular interest to the mussel industry. More detailed information can be obtained here.

     

     

  • Patent | Procedure for the extraction of hyaluronic acid from fish vitreous humor

    Authors: Miguel Anxo Murado; Maria Montemayor Castroviejo; Marta López Cabo; Maria del Pilar Gonzalez Fernández; Laura Pastoriza Enriquez

    Technique for the preparation of hyaluronic acid (AH) based on fish vitreous humor for its use in cosmetics and clinical work. The process comprises protein electrodeposition and simultaneous diafiltration with total recirculation. This procedure allows for selective recovery of impure sediments, precipitation of AH and solubilization of proteins, yielding AH with purity over 99.5%. More detailed information can be found here.

     

     

  • Patent | An optimal operation for nisin production

    Authors:  Marta López Cabo; Miguel Anxo Murado García; M P Gonzalez Fernández; Laura Pastoriza Enriquez; Juan Jose Rodriguez Herrera; Lorenzo Miguel Pastrana Castro

    Method for nisin production in submerged culture based on reiterated re-alkalinization of the medium, provided that the culture maintains the capacity to recover its level of stabilization, combined with a discontinuous glucose feeding regime. More detailed information can be found here.

     

     

     

  • Patent | Procedure for the identification of albacore (Thunnus alalunga) in canned tuna

    Authors: Carmen González Sotelo; Isabel Medina; Ricardo Pérez Martín; Javier Quinteiro Vázquez; Manuel Rey Méndez

    Technique for the identification of Thunnus alalunga in preserved tuna products, which comprises the amplification of a 187-pb fragment (BDR) of the cytochrome b gene in mitochondrial DNA by the sequential use of two endonucleases. This allows distinguishing it from other species used as substitutes for Thunnus alalunga in canned products. More detailed information can be found here.

     

     

  • Patent | Procedure for the identification of frigate mackerel (Auxis thazard) in canned frigate mackerel

    Authors: Carmen González Sotelo; Isabel Medina; Ricardo Pérez Martín; Javier Quinteiro Vázquez; Manuel Rey Méndez

    Technique for the identification of Auxis thazard in preserved fish products, which consists of the amplification of a 187-pb fragment (BDR) of the cytochrome b gene in mitochondrial DNA by the use of a restriction endonuclease. This allows distinguishing it from other species used as substitutes for Auxis thazard. More detailed information can found here.

     

  • Patent | Differentiation of various tuna species in canned tuna products

    Authors: Carmen González Sotelo; Isabel Medina; Ricardo Pérez Martín; Javier Quinteiro Vázquez; Manuel Rey Méndez

    Technique for the differentiation of various tuna species in canned tuna products, consisting of the sequential use of a set of restriction endonucleases on an amplified 187-bp fragment known as bdr of the b cytochrome in the mitochondrial ADN. Thus, Thunnus thynnus, T. obesus, T. albacares and Katsuwonus pelamis are distinguished by fragment analysis. More detailed information can be found here.

     

  • Capabilities | Development of “in vivo” bioactivity tests for biomolecules using animal models

    Use of animal models (zebrafish, turbot, mice, etc.) as model systems to study the bioactivity of different compounds, as well as fish and human diseases (septic shock, inflammatory illnesses, etc.).
