Efecto inhibidor del dióxido de germanio sobre el biofouling del puerto de Mar del Plata

Abstract

Marine biofouling on any newmaterial immersed in seawater can lead to extra costs due to increased maintenance,or/and even mechanical wear, and/or biodeterioration that require costlyantifouling measures. Fouling organisms growing on immersed manmade surfacesaffect hulls, piers, buoys, aquaculture and pipes mainly. Following adsorptionof a conditioning film of macromolecules, microorganisms which are the primarycolonizers (microfouling), are found on unprotected surfaces after only a fewminutes of immersion. Extracellular polymeric material exudates from bacteriaforms a net that permits anchorage and protection for spores of macroalgae andmacroinvertebrate larvae which arrive later. This community is called?biofouling? and develops a thick layer rapidly. As a consequence, the searchis orientated to new efficient compounds to formulate environmental friendlyantifouling paints
