| Today, the seaweed industry's main products are the alginates and carraghenanes. The industrial network faces many problems. However, it remains prosperous since it ranks fifth in the world for alginate production and third for caraghenanes'. This stability which seems safe on a middle term standpoint must not conceal the crisis which previously hit Fucus' exploitation. Rightly so, being harvested until approximately 1950 for soil amendment purposes, coastal kelp (i.e. Fucus), was replaced by chemical fertilizers. Brittany's production which was reaching 180 000 cubic metre in the twenties, close to 200 000 tons of fresh kelp, would have become non existent if it had not been converted into seaweed meal for livestock feed. The market demand was then... |

| Haemocytes are the key elements of a complex defence system on which crustacean immunity is largely based. We report here for the first time in a crustacean that haemocytes are involved in the synthesis of antimicrobial peptides similar to those described in other arthropod classes. These molecules isolated from the penaeid shrimp Penaeus vannamei are members of an homogeneous farnily which differ from the antimicrobial peptides previously described in that they combine in a single molecule a proline-rich arninoterminal domain, and a cyclic carboxy-terminal domain containing three intramolecular disulphide bridges. In addition, penaeidins bear post-translational modifications at their arnino- and carboxy-termini. Five molecules of the penaeidin family were... |

| Cette étude doit être replacée dans une série de travaux ayant pour but de mieux connaître les caractères des protéines du milieu intérieur des crustacés. En effet, malgré plusieurs publications importantes concernant ce sujet, de nombreuses inconnues subsistent encore quant à la connaissance des protéines de l'hémolymphe, quant à leurs différences suivant le sexe des individus étudiés à l'intérieur de l'espèce considérée, quant à leurs variations, chez les femelles, en fonction des différentes phases de l'ovogenèse. Il est rendu compte ci-après des résultats obtenus après électrophorèse, en vue d'analyser les composants protéiques de l'hémolymphe du crustacé Processa edulis edulis |
