Definitions

• the invention relates to the capture of natural substances produced by a marine invertebrate or an invertebrate colony in their natural environment.
• the invention relates to the capture of organic molecules from an aquatic environment by means of a device for extracting a fluid from an aquatic environment for trapping chemical compounds from such a medium as well as a module for the implementation of such a device.
• Bioactive natural products are the preferred source for the discovery of active drugs on various pathologies (cancer, infections, neurodegenerative diseases, immune diseases ). Natural products are isolated from various bioresources. Of these bioresources, marine invertebrates are an important source.
• Marine invertebrates are animals that die quickly once removed from their natural ecosystem, ecosystem in which they live in permanent interaction with other organisms associated with them (microorganisms, microalgae, annelids, bivalves ). Marine invertebrate is thus termed holobionte, a term that indicates an organism consisting of the association of several interdependent species.
• Marine invertebrates are increasingly rare in nature and are subject to various climatic (global warming) and anthropogenic (intensive harvesting, non-selective uprooting, poaching ...) stresses. In addition to these stresses, marine invertebrates are for many endangered, difficult to cultivate, difficult to collect when they colonize inaccessible sites, difficult to ship and keep alive.
• invertebrate cells by growing invertebrate cells. These solutions are not satisfactory, however. Indeed cell culture is anecdotal for purposes of basic research exclusively. The culture of marine invertebrates is extremely slow and uncertain before reaching exploitable quantities. In addition, the invertebrate is studied outside its habitat and the conditions that characterize it, and without its natural symbionts associated with it.
