Microaerobic Tolerance and Growth Analysis of Organohalide-Respiration and Uranium-Reducing Geobacter lovleyi Strain SZ

Oxygen intrusions in shallow and high-recharge aquifers disrupt anaerobic bioremediation, often hindering the reduction of harmful contaminants like tetrachloroethylene (PCE) and hexavalent uranium [U(VI)]. This is particularly problematic for microorganisms like Geobacter lovleyi strain SZ, which is important in reducing these co-contaminants in strict anaerobic conditions. Recent observations have challenged its strict anaerobe classification, suggesting potential oxygen tolerance. The research aims to determine the extent of oxygen tolerance of Geobacter lovleyi to broaden the understanding of bioremediation strategies in dynamic subsurface environments. These insights lead to more effective contamination cleanup and containment practices to safeguard public health.
