Abstract: A material for reducing the content of polluting and/or unwanted substances in a liquid includes at least one polymeric and/or inorganic base, suitable to be immersed in the liquid, having at least a surface, whereto is bonded at least one catalyst of the degradation reaction of inorganic salts in gaseous substances. The catalyst, whose function is to reduce the energy required for the activation of said reaction and to accelerate its progress, is an enzyme preferably selected among the lyase group, the hydrolase group and the oxidoreductase group.

Abstract: A device for reducing the content of polluting and/or unwanted substances in water, including a support made of polymeric material for a catalyst of the reaction of degradation of inorganic salts into gaseous substances; the catalyst, intended to reduce the energy required for the activation of the reaction and to accelerate its course, is an enzyme preferably selected from the group of lyases, and even more preferably selected from the subgroup of carbonic anhydrases. The inorganic are being carbonates, and/or hydrogen carbonates of calcium and/or magnesium, the reaction being the reaction of decarboxylation and acting for the conversion of inorganic salts into carbon dioxide and water according to the following reaction: HCO3?+H+H2O+CO2.

Abstract: A method for preventing and controlling the formation of biofouling on an object that is immersed or partially immersed in a water environment in which there is one or more organic or inorganic compounds capable of releasing gas, comprising the step of applying to the surface of the object a composition comprising a polymeric resin and one or more enzymes or a paint or a coating and one or more enzymes, wherein the one or more enzymes are adapted to catalyze a reaction of the one or more compounds that leads to the formation of gas.

Abstract: Method for preventing and controlling organisms that infest aqueous systems in which one or more organic or inorganic compounds capable of releasing gas are present, comprising the step of dispersing on and/or in the aqueous mass a preparation comprising enzymes adapted to catalyze a reaction of the one or more compounds that leads to the formation of gas.
