Bioremediation of soil

In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

Enhanced Bioremediation

Introduction Enhanced bioremediation is a process in which indigenous or inoculated micro-organisms (e.g., fungi, bacteria, and other microbes) degrade (metabolize) organic contaminants found in soil and/or ground water, converting them to innocuous end products. Nutrients, oxygen, or other amendments may be used to enhance bioremediation and contaminant desorption from subsurface materials. ...

Biotechnology of hydrocarbon bioremediation in soil washing slurry

Application of Bioremediation for low cost contaminated soil washing slurry treatment with quick hydrocarbon reduction and improved sustainability. The application uses proprietary microbial formulation with a slurry bioreactor in order to accelerate the degradation process and to make it compatible with soil washing technology. The end result is a treated soil which meets the requirements for ...

Bioremediation of Kerosene and Diesel Fuel in soil case study

The United States has a large hazardous waste problem that is threatening both human health and the environment. Current analysis of the nearly 1,200 National Priority List (NPL) sites reveals that about 80% of the sites are contaminated with organic compounds. Clean-up of hazardous waste sites, as a national priority has accelerated the development of bioremediation technologies. Environmental ...

Bioremediation replaces “dig and dump” for treatment of pesticides in soil

Historical usage of organochlorine pesticides (OCPs) such as DDT, toxaphene and dieldrin has resulted in long-term soil contamination, because these substances typically do not degrade naturally at significant rates, so sites are still impacted decades after the end of application. For example, DDT use in Canada ended over 30 years ago, but impacted soil remains at many sites. Such was the case ...

A Citizen`s Guide to Bioremediation

What is bioremediation? Bioremediation is a treatment process that uses naturally occurring microorganisms (yeast, fungi, or bacteria) to break down, or degrade, hazardous substances into less toxic or nontoxic substances. Microorganisms, just like humans, eat and digest organic substances for nutrients and energy. In chemical terms, 'organic' compounds are those that contain carbon and hydrogen ...

Surfactant enhanced bioremediation (SEB)

Surfactant Enhanced Bioremediation (SEB®) using Ivey-sol® involve the use of Ivey-sol formulations which are patented non-ionic surfactant mixtures used in the in-situ and ex-situ treatment of petroleum hydrocarbons, heavy metals, and more recently radioactive type contaminated waste. These surfactant formulations have the ability to enhance soil biodegradation. During In-situ and Ex-situ ...

Bioremediation of an Oil Spill

Bioremediation is the method of choice to effectively clean up a small spill of hydrocarbons. In this case, five-hundred liters of BTEX has spilled from an above ground storage tank into a pasture that is located at the west edge of the Royal Roads University (RRU) grounds. The soil is classified as a Gleyed Eutric Brunisol based on recent laboratory analysis; it contains clay, but is fairly ...

Bioremediation with compost of a diesel contaminated soil: Monitoring by dehydrogenase activity and basal respiration

The effect of compost on hydrocarbon degradation was determined during a 120-d incubation period. An evaluation of soil basal respiration and dehydrogenase activity as a monitoring instrument for the bioremediation process of soil contaminated with commercial diesel-oil was carried out. Six soil samples were used: S (control, uncontaminated soil), CS (contaminated soil), CSS (contaminated and ...

Types of bioremediation and their modes of action

An Urgent Call for Change in U.S. Oil Spill Response With Bioremediation Agent Type EA* bearing out as a workable first response alternative to the use of chemical dispersants, contrasting evidence has become even clearer that dispersant use has been a huge failure. Dispersants have proven to be an inadequate response method with more and more studies showing an ...

Bioremediation of PCB & Pesticide Contaminated Soils Utilizing Gene Expression Factors

Abstract Historically soils contaminated by persistent organic compounds such as pesticides and PCBs were not considered good candidates for bioremediation due to the simple fact that the chemical industry designed these compounds to withstand the destructive effects of natural attenuation through weathering and microbial activity. Although the chemical industry has long appreciated the ...

A Tale of Two Sites - Enhanced Bioremediation of Explosives Impacted Soils

The problem with OE compounds in soil A variety of organic explosive (OE) compounds have been used for military, geological and industrial applications throughout North America, and in most industrialized nations. During their manufacture, formulation and storage, these compounds have migrated to the soil. Compounds such as 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine ...

CL-Out In Situ Bioremediation of Perchlorate

CL-Out is a consortium of facultative aerobic organisms that are well know for their ability to utilize nitrates. CL-Out is generally used for the aerobic cometabolism of PCE and other chlorinated solvents. As the half-reaction for perchlorate is close to that of nitrate, CL-Out cometabolism of perchlorate was successfully tested in the laboratory. In addition to laboratory ...
