Presently, there are several thousand diesel-contaminated sites in sub-Arctic Canada. Bioremediation is a sustainable approach that utilizes the soil’s indigenous bacteria to degrade diesel to less toxic intermediates; however, its success rate is inconsistent. Current bioremediation practices rely on nutrient addition but do not consider bio-accessibility limitations. By analyzing different sub-Arctic soils to identify correlations between bioremediation success and sub-micron microhabitats and soil microbiology, Anirban’s research addresses this gap. Future implications of this research will assist practitioners in using bioaccessibility in addition to nutrient requirements to increase bioremediation success
