Abstract

L'invention concerne une méthode, un système et un appareil de production de peroxyde d'hydrogène pour produire de grands volumes de peroxyde d'hydrogène ayant des concentrations supérieures ou égales 80 % dans un cycle continu. Dans un aspect, la méthode peut comprendre le mélange d'une enzyme NQO1, d'un composé ou d'une molécule activée par NQO1, et d'un cofacteur NADH ou NADPH avec une solution aqueuse, la distribution de la solution aqueuse dans ou sur une membrane semi-perméable, la membrane semi-perméable comprenant en outre une barrière de poids moléculaire prédéfini. De plus, une réaction d'oxydoréduction de l'enzyme NQO1, du composé ou de la molécule activée par NQO1, et du cofacteur NADH ou NADPH dans la solution aqueuse produit du peroxyde d'hydrogène à un niveau de concentration. Ici, le peroxyde d'hydrogène produit est au-dessus de la barrière de poids moléculaire prédéfini de la membrane semi-perméable et diffuse à travers la membrane semi-perméable pour être extrait pour utilisation.
