Bioremediation involves the use of living organisms to clean up the environment.

The U.S. creates 300 million metric tons of biohazardous waste every year from households and industry: the chemical industry single-handedly generates approximately five million tons of waste and more than 1/2 these are let loose into the environment.

Numerous organic contaminants are carcinogenic, break down very slowly, and tend to collect within the environment posing noteworthy health hazards to human and other living organisms. Bioremediation involves the use of plants (phytoremediation) and microorganisms to treat contaminated soil and water in an environmentally friendly manner. This article will focus on the use of microorganisms to take care of contaminated sites.

Microorganisms are employed in a variety of methods to decontaminate polluted places and stimulate the environment. Microbial remediation involves natural attenuation, biostimulation and/or bioaugmentation. All three processes rely on the capacity of microorganisms to break down the complex molecules of chemicals in biohazardous waste and use these simpler ...
... molecules to create cell parts; thereby, keeping their particular metabolic processes.

Natural attenuation (intrinsic or natural bioremediation) relates to the process that happens naturally in contaminated soil or water, as petroleum, gas and oil are lessened by oil-degrading microorganisms local to the soils at contamination locations. An example would be the natural process that occurs at old gas stations with leaky underground tanks: oil-degrading microorganisms present in the soil will eventually break down the contaminants. However, researchers are investigating solutions to broaden the scope of contaminants that microorganisms could digest, sort of like teaching bacteria to eat new things, and maybe even speed up the process.

Biostimulation involves the addition of nutrients and oxygen to contaminated water or soil to encourage bacterial growth and activity. Biostimulation was used following the grounding of the Exxon Valdez when fertilizer applications were applied to the contamination site to stimulate growth of indigenous oil-degrading microorganisms.

Natural attenuation and biostimulation both rely on the natural presence of microorganisms which will degrade the specific contaminant. As an example, following the grounding of the Exxon Valdez, the expansion of naturally occurring oil-degrading bacteria was promoted so microbial degradation of the oil could occur quicker.

Whereas natural attenuation and biostimulation depend on indigenous microorganisms, bioaugmentation is employed at sites where chemical-specific degrading microorganisms usually are not found. Bioaugmentation involves adding particular microorganisms to contaminated soil or water in the contamination site or in a treatment facility (e.g. municipal wastewater treatment facility). Indigenous microorganisms, with a “taste” for that kind of contaminant, are isolated from other contamination sites of the same “flavour”, and added to the contaminated soil or water.

The bioremediation products are one of the best ways to oil spills clean up and also one of the most natural ways for oil spill remediation. Catalina BioSolutions BioCritters and services have cleaned over 1,000 sites effectively, efficiently and affordably.
