Abstract: A method for remediating bacterially-induced corrosion, environmental damage, and/or process inefficiencies in an industrial process includes identifying an industrial process where target bacteria adversely affect corrosion, environmental impact, and/or process efficiencies. The process also includes identifying the strains of the target bacteria, obtaining a bacteriophage virulent against one or more of the strains of the target bacteria, and exposing the target bacteria to the bacteriophage. The method can utilize an aqueous composition comprising bacteriophage encapsulated in at least one selected from the group consisting of: liposomes, foam, and gel.
