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. ...

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 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 ...

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 ...

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 ...

Fast bioremediation of a hydrocarbon contaminated site

The use of bioremediation has been demonstrated to be a very effective treatment technology for a hydrocarbon contaminated site within a month of starting. In addition to selection and preparation of an appropriate microbial inoculum the other key considerations were effective mixing, addition of suitable nutrients and maintenance of soil moisture levels. Careful management of all these ...

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 ...

Innovative Uses of Compost Bioremediation and Pollution Prevention

Each year agricultural effluents, industrial residues, and industrial accidents contaminate surface waters, soils, air, streams, and reservoirs. A new compost technology, known as compost bioremediation, is currently being used to restore contaminated soils, manage stormwater, control odors, and degrade volatile organic compounds (VOCs). Compost bioremediation refers to the use of a biological ...

Natural Attenuation in Soils

Introduction Surface and subsurface soils have different characteristics in natural attenuation. Mobile contaminants in subsurface soils diffuse into soil vapor and aqueous phase and thus are relatively easily subject to natural subsurface processes that can attenuate these contaminants. Most high-molecular-weight (persistent) organic and many inorganic contaminants will be immobilized in the ...
