Since the discovery of agar plates, which enabled scientists to isolate diseases such as tuberculosis and cholera, bacteriological agar has been obtained from red algae of the Gelidium genus. This type of agar is especially valued by research centers, universities and specialized laboratories, where it is used as a culture medium for microorganisms and in molecular biology techniques, such as agarose gels.

Portugal has ideal natural conditions for the production of this algae species, as evidenced by its natural abundance. The country benefits from a privileged geographical position, with an extensive coastline, strong hydrodynamic seas and a sunny climate, factors that make Portugal a strategic location for the production of Gelidium. The harvesting, production and processing of algae are commercial activities of great relevance to the Blue Economy, contributing significantly to sustainable development and the enhancement of marine resources.
