TL;DR: In this article, the role of PAH bioavailability in the biodegradation of polycyclic aromatic hydrocarbons in 'pristine' soils from different climatic regions is discussed as well as the factors that control it.
Abstract: Polycyclic aromatic hydrocarbons (PAHs) are an important class of organic contaminants ubiquitously found in soils globally. Their fate in soil varies depending on both soil properties and chemical structure; however, microbial degradation represents the most significant means of loss. It is therefore important to understand the factors that control PAH biodegradation in different soil environments. This review considers PAH biodegradation in "pristine" Antarctic, temperate, tropical and hot desert soils. Pre-exposure of indigenous microbes to PAHs is important for the development of the capacity to degrade PAHs so PAH sources to these soils are discussed. The role of PAH bioavailability in the biodegradation of PAHs in 'pristine' soils from the different climatic regions is also discussed as well as the factors that control it. Soil organic matter, water content and temperature are seen as the main environmental factors that control PAH bioavailability in these soils. With most studies focussing on temperate soils, there is need for more research on soils from other climatic zones.

Journal ArticleDOI
TL;DR: The results show that during the initial stages of composting, DOM is highly degradable under aerobic conditions, particularly due to the predominance of labile, hydrophilic compounds such as carbohydrates, amino acids and proteins.

TL;DR: Bioremediation is a technology that can be used to reduce, eliminate, or contain hazardous waste over the past two decades, it has become widely accepted that microorganisms and to a lesser extent plants, can transform and degrade many types of contaminants These transformation and degradation processes vary, depending on physical environment, microbial communities, and nature of contaminant as mentioned in this paper.
Abstract: This primer is intended for people interested in DOE environmental problems and in their potential solutions It will specifically look at some of the more hazardous metal and radionuclide contaminants found on DOE lands and at the possibilities for using bioremediation technology to clean up these contaminants Bioremediation is a technology that can be used to reduce, eliminate, or contain hazardous waste Over the past two decades, it has become widely accepted that microorganisms, and to a lesser extent plants, can transform and degrade many types of contaminants These transformation and degradation processes vary, depending on physical environment, microbial communities, and nature of contaminant This technology includes intrinsic bioremediation, which relies on naturally occurring processes, and accelerated bioremediation, which enhances microbial degradation or transformation through inoculation with microorganisms (bioaugmentation) or the addition of nutrients (biostimulation)
