Compositions and methods are provided for use in controlling souring and corrosion causing prokaryotes, such as SRP, by treating oil and gas field environments or treatment fluids with a newly identified bacterial strain ATCC Accession No. PTA-124262 as a self-propagating whole cell that produces an anti-SRP bacteriocin in situ. In another aspect, the methods use one or more toxic peptides or proteins isolated therefrom in methods to control unwanted prokaryotic growth in these environments.

Compositions and methods for remediation of sulfate reducing prokaryotes

There is provided a safe, natural, environmentally sound means of controlling bacterial contamination, corrosion, and souring of oil and gas wells and reservoirs that result from bacteria-contaminated water in a well. In one aspect it is a process for remediation of souring of petroleum reservoirs and coalbeds by adding to the water used in flooding and 'fracing' operations an effective amount of virulent (non-lysogenic) bacteriophages (phages) specific for problematic target bacteria. The invention also provides a means for combating loss of effectiveness of bacterial control by staging bacteriophage production and application to control dominant and sub-dominant target bacteria in a community of target bacteria.

Prevention and remediation of petroleum reservoir souring and corrosion by treatment with virulent bacteriophage

A process for remediation of target bacteria, particularly sulfur reducing bacteria (SRB), in waters ('target water') having a multiplicity and diverse host target bacteria by employing serial or staged bacteria culturing and lysing of dominant bacteria. Remediation of sulfur reducing bacteria (SRB) is effected by application of a series of bacteriophage isolated from the staged culturing and bacteriophage lysing of successive aliquots of waters containing a multiplicity of SRB.

Staged bacteriophage remediation of target bacteria

A method of reducing process interruptions in biofuel production systems by reducing the amount of unwanted bacteria in the biofuel production system in which the reduction is effected by the use of an effective amount of one or more types of bacteriophages virulent for at least some strains of the unwanted bacteria.

Application of bacteriophages for the control of unwanted bacteria in biofuel production mediated by non-bacterial reactive agents

A method of controlling filamentous bacteria responsible for foaming and bulking in wastewater systems with virulent bacteriophage. The method includes, optionally, identification of problematic filamentous bacteria and matching virulent bacteriophage, use of bacteriophage from phage libraries and concentration of filamentous bacteria and bacteriophage from the wastewater to be treated.

Control of filamentous bacteria induced foaming in wastewater systems

Bacterial contamination of industrial water systems lead to biofouling by biofilms and corrosion from bacterial induced corrosion. This invention provides a method for control of fouling and contamination of industrial water systems caused by bacteria. Prevention or reduction of process interruptions and general contamination, fouling and corrosion is achieved by the destruction of targeted problematic bacteria with naturally occurring, non-engineered bacteriophage virulent for targeted bacteria. The invention also provides for in-situ confirmation of the proper identification of target bacteria and a mobile laboratory adapted to implement the method.
