Bioremediation of Crude Oil- Contaminated Soil Using Slurry-Phase Biological Treatment and Land Farming Techniques

Screening Effective Factors in Slurry Phase Bioremediation of 2,4,6-Trinitrotoluene (TNT) Contaminated Soil

Effects of humic substances and soya lecithin on the aerobic bioremediation of a soil historically contaminated by polycyclic aromatic hydrocarbons (PAHs).

The high hydrophobicity of polycyclic aromatic hydrocarbons (PAHs) strongly reduces their bioavailability in aged contaminated soils, thus limiting their bioremediation. The biodegradation of PAHs in soils can be enhanced by employing surface-active agents. However, chemical surfactants are often recalcitrant and exert toxic effects in the amended soils. The effects of two biogenic materials as...

Effects of different remediation treatments on crude oil contaminated saline soil.

Remediation of the petroleum contaminated soil is essential to maintain the sustainable development of soil ecosystem. Bioremediation using microorganisms and plants is a promising method for the degradation of crude oil contaminants. The effects of different remediation treatments, including nitrogen addition, Suaeda salsa planting, and arbuscular mycorrhiza (AM) fungi inoculation individually...

Bioremediation of organic contaminated soils*

The term bioremediation covers a wide variety of engineered systems which utilize microorganisms to degrade, detoxify and immobilize organic contaminants. These systems include: l solid-phase treatment using unlined iand treatment systems or prepared bed bioreactors, l slurry-phase treatment systems completed either in-place or within tanks or impoundments, and l in situ treatment systems. Bior...

BIOREMEDIATION OF CRUDE OIL CONTAMINATED SOILS A Black Art or an Engineering Challenge?

A bioremediation of crude oil contaminated soils study was carried out in engineered laboratory biopile systems. In soil bioremediation, biopiles are ‘ex situ’ treatment systems that consist of excavated and aerated contaminated soils amended by addition of biological, mineral or organic material depending upon specific needs. When bacteria are added to the contaminated soil undergoing biologic...
