A method of regenerating an enzymatic catalyst arranged in a reactor includes a mineral support based on metal oxide and at least one enzyme, wherein it contains at least one step of detachment of the spent enzymes by solvation by scavenging of the catalyst using at least one ionic surfactant, and at least one step of re-attachment of active enzymes by scavenging of the purified support with at least one solution of active enzymes, the two steps being performed in situ within the reactor.
