Estandarización del método de obtención de extractos y fracciones de organismos marinos e incorporación en geles inertes para ensayos de evaluación antifouling

Abstract

The fouling is a natural phenomenon that has become a problem of enormous proportions for the maritime industry, not only for its direct effects on boats and underwater structures and the economic implications it brings, if not by the injurious effects that have created solutions in order to neutralize them. Thus, the Marine Natural Products (MNP) appears as an alternative, given that many marine organisms have already found a solution to avoid being pressured by the fouling and could be the source of active ingredients that can be used in coatings or paints effective against the spread of fouling organisms on the surfaces of submerged structures, contributing to reduce the impact on the ecosystems. The search for antifouling agents from marine organisms requires certain approximations techniques for separating substances from the tissues for evaluation. This document describes the standard techniques in the Marine Bioprospection Laboratory INVEMAR (LABBIP) for the preparation of extracts and fractions of marine organisms and their inclusion in inert gels, one of the field techniques that allow evaluating the potential antifouling in natural environment.
