Claims54
A method for controlling growth, in an aqueous system, of microorganisms which adhere to walls and other structural surfaces of the system, which method comprises providing to said aqueous system a composition comprising a chelating agent and an antimicrobial compound in an amount at least effective to control said growth.
A method for controlling, in an aqueous system, the biofouling of the walls and other structural surfaces of the system by a microorganism, said method comprising providing to said system a composition comprising a chelating agent and an antimicrobial agent in an amount at least sufficient to control said biofouling.
A method for removing or reducing formation of a biofilm in an aqueous system comprising providing to said system a composition comprising a chelating agent and an antimicrobial agent in an amount at least sufficient to remove or reduce formation of said biofilm.
A method for inhibiting the growth of a microorganism, comprising contacting said microorganism with a composition comprising a chelating agent and an antimicrobial agent in an amount at least sufficient to inhibit the growth of said microorganism.
A method for controlling the growth of microorganisms on the interior surface of a pipe, comprising contacting said surface with a microbicidally-effective amount of a composition comprising an antimicrobial agent and a chelator.
A method for inhibiting the growth of a bacterium, comprising contacting said bacterium with a composition comprising a chelating agent and an antibiotic in an amount at least sufficient to inhibit the growth of said bacterium.
A method for controlling the growth of bacteria on the interior surface of a pipe, comprising contacting said surface with a bactericidally-effective amount of a composition comprising an antibiotic and a chelator.
A method for inhibiting the growth of a fungus, comprising contacting said fungus with a composition comprising a chelating agent and an antifungal agent in an amount at least sufficient to inhibit the growth of said fungus.
A method for controlling the growth of fungi on the interior surface of a pipe, comprising contacting said surface with a fungicidally-effective amount of a composition comprising an antifungal agent and a chelator.
