Bioremediation of oil-contaminated soil : a South African case study.
In 1990, an oil recycling plant situated in Hammarsdale, South Africa, was decommissioned and a decision was taken by management to rehabilitate the site in preparation for resale. The heavily impacted area covered over ...
Bioremediation of creosote-contaminated soil by microbial intervention..
No abstract available.
Exploitation of indigenous fungi in low-cost ex situ attenuation of oil- contaminated soil.
The central aim of this study was to determine if indigenous fungi of an oil-contaminated soil could be effectively used in a low-cost bioremediation of the soil. Since some of the contaminant had been present at the ...
Molecular and physiological characterization of thiosulphate-oxidizing microbial associations prior to use in hydrogen sulphide biofiltration.
Interacting microbial associations capable of utilizing thiosulphate as an energy source were enriched/isolated from activated sludge, landfill site [mal covering soil and soil from an acid mine water drainage site. The ...
Bioremediation of chemically contaminated soil : extraction/analysis methodology development.
The efficacies of soil extraction methods, namely, Soxhlet, sonication, agitation, alkaline digestion and the ethyl acetate micro-method, for monitoring soil bioremediation were evaluated using three soil types, Swartland, ...
Development of a bioreactor system using a pine bark matrix for the removal of metal ions from synthetic aqueous solutions.
Many industries use, or produce, metal-containing solutions which must be treated for reuse or discharge to sewer. One such treatment is biological and both living and dead materials have been investigated for the abstraction ...
Bioremediation of heavy metal polluted waters.
Microorganisms have the potential to remove heavy metals from polluted waters and effluents and may be used in clean-up processes. Microbial associations were enriched for and adapted to grow in nutrient solutions ...
Humic acid pretreatment for enhancing microbial removal of metals from a synthetic 'wastewater'.
The presence of heavy metal ions in waste streams is one of the most pervasive environmental issues of present times. A rotating biological contactor (RBC) was used to investigate the potential capacity of microbial ...
The microbiology of ex situ bioremediation of petroleum hydrocarbon-contaminated soil.
Bioremediation is the process whereby the degradation of organic polluting compounds occurs as a result of biochemical activity of macro- and microorganisms. Bioremediation of hydrocarbon contaminated soils can be practised ...
Strategies for effective bioremediation of water co-contaminated with 1, 2-dichloroethane and heavy metals.
The production of 1,2-Dichloroethane (1,2-DCA) exceeds 5.44 billion kg per year, and is higher than that of any other industrial halogenated chemical. Improper disposal practices or accidental spills of this compound have ...
