PhD Scholarship in Molecular studies of biosurfactant control of bacterial PAH degradation in soil
Department of Agriculture and Ecology, Faculty of Life Sciences at University of Copenhagen is offering a PhD scholarship commencing 1st February 2011 or soon thereafter. The application deadline is 15 December 2010.
Petroleum hydrocarbons have been extensively exploited through human activities for many years and mineral oil contaminations of soils, sediments and groundwater represent a huge problem world-wide. Bioremediation, which is the use of living (micro)organisms for removal of contaminants from the environment, is today a cost-efficient approach to treat soil and sediments contaminated by PAHs.
Importantly the limited bioavailability / bioaccessibility of the hydrophobic PAHs represents an important bottleneck leading to low rates of pollutant loss. The challenge posed by limited PAH bioavailability / bioaccessibility may be addressed by addition or in-soil production of biosurfactants. Addition of biosurfactants is already known to lead to increased solubility of PAH compounds further stimulating biodegradation. In situ production of biosurfactants are documented to play important roles in bacterial motility, affecting attachment / detachment to surfaces and biofilm formation, whereas there are few (if any) reports addressing the significance of in situ production of biosurfactants for biodegradation at a mechanistic level.
The aim of the PhD project is to reveal the significance of in situ production of biosurfactants in PAH-degrading bacteria for their ability to access and degrade hydrophobic oil contaminants in soil as determined by degrader gene expression and contaminant turn-over.
The hosting laboratory has extensive experience in molecular microbial research related to soil microbiology in general and bacterial soil and rhizosphere colonization, metabolic and degradation activity, gene expression, etc. The project will be associated with the Center for Environmental and Agricultural Microbiology – A VKR Centre of Excellence, hosted by the laboratory and further takes advantage from ongoing project collaborations with Danish, industrial partners within in soil remediation and with international research partners in Germany and Spain.
