Bioremediation by catalina006
What is Bioremediation?.....it is the use of living organisms to clean up the environment.
The U.S. creates 300 million metric tons of biohazardous waste annually from households and industry: the chemical industry single-handedly generates approximately 5 million tons of waste and on average 50% of these are released into the environment.
Loads of organic contaminants are carcinogenic, break down very slowly, and tend to accumulate in the environment posing considerable health risks to human and other living organisms. Bioremediation involves the utilization of plants (phytoremediation) and microorganisms to take care of contaminated soil and water in an environmentally friendly method. This article will focus on the use of microorganisms to handle contaminated locations.
Microorganisms are used in a variety of methods to decontaminate polluted spots and stimulate the environment. Microbial remediation involves natural attenuation, biostimulation and/or bioaugmentation. All three processes rely on the ability of microorganisms to break down the complex molecules of chemicals in biohazardous waste and utilize these simpler molecules to develop cell parts; thereby, preserving their unique metabolic processes.
Natural attenuation (intrinsic or natural bioremediation) would be the process that occurs naturally in contaminated soil or water, as petroleum, gas and oil are counteracted by oil-degrading microorganisms indigenous to the soils at contamination locations. An example is the natural process that happens at old gas stations with leaky underground tanks: oil-degrading microorganisms present in the soil will eventually break down the contaminants. But, researchers are investigating ways to broaden the scope of contaminants that microorganisms might digest, almost like teaching bacteria to eat new things, and maybe even speed up the process.
Biostimulation involves the adding together of nutrients and oxygen to contaminated water or soil to promote bacterial growth and activity. Biostimulation was used following the grounding of the Exxon Valdez when fertilizer applications were introduced into 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. For 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 used 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 at 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.
Microorganisms are used in a number of solutions to decontaminate polluted areas and stimulate the environment. Microbial remediation calls for natural attenuation, biostimulation and/or bioaugmentation. All three processes rely on the ability of microorganisms to break down the complex molecules of chemicals in biohazardous waste and use these simpler molecules to develop cell parts; thereby, sustaining their unique metabolic processes.
Natural attenuation (intrinsic or natural bioremediation) is the process that occurs naturally in contaminated soil or water, as petroleum, gas and oil are diminished by oil-degrading microorganisms local to the soils at contamination areas. An example could be the natural process that happens at old gas stations with leaky underground tanks: oil-degrading microorganisms within the soil will eventually break down the contaminants. But, researchers are investigating methods to broaden the scope of contaminants that microorganisms would be able to digest, almost like teaching bacteria to eat new things, and maybe even speed up the process.
