bacteria that require oxygen to survive and multiply.

n pi: bacteria that require free oxygen for their life processes. Aerobic bacteria can produce slime or scum, which accumulates on metal surfaces, causing oxygen-concentration cell corrosion.

remediation technique to strip volitile contaminants from contaminated ground water after a spill. Works to oxidize components and to activate bacteria that can digest hydrocarbons.

bacteria that can survive and multiply without oxygen.

n pi: bacteria that do not require free oxygen to live or that are not destroyed by its absence. Under certain conditions, anaerobic bacteria can cause scale to form in water-handling facilities in oilfields or hydrogen sulphide to be produced from sulphates.

n pl: a large, widely distributed group of typically one-celled microorganisms. See anaerobic bacteria, sulfate reducing bacteria.

n: Refers to the microbe that makes drilling fluid decrease filtration rate and viscosity due to it can destroy amylum additive.

n: The process that superpolymer is destroied by the microbe and macromolecule fractures to micromolecule.

breaking down alkanes by bacterial action. Common by psedomonis and ultramonis bacteria and other bacterial strains that digest parts of the crude oil structures. Useful for remediating oil spills or tank bottom residuals.

n: anything that destroys bacteria.

n: The additive used to kill the bacterias in drilling fluid.

a product that kills bacteria in the water or on the surface of the pipe.

remediation technique that introduces natural hydrocarbon digesting bacteria and materials such as enzymes to remove hydrocarbons from soil, water or even air.

bacteria generated natural gas, found at shallow depths and in many water wells. Usually contains C14 isotope. See also thermogenic gas as a gas that has a biological origin but has been modified from the original organic state by time at temperature and
