Abstract

Soil quality is declining at a rapid rate on a global scale. Much of this decline is attributed to chemical contamination by humans. Bioremediation, the use of living organisms for decontamination, offers a mechanism for restoring both aquatic and soil habitats. Bioremediation often involves biodegradation of contaminant by the action of microbial enzymes. Given the high microbial density in soil and the diversity of enzymes encoded in their genomes, the chances of isolating bioremediating bacteria from soil are quite promising. The aim of this project is to isolate and characterize bacterial strains from soil that are capable of degrading pesticides and total petroleum hydrocarbons. Using soil samples from local agricultural fields, strains resistant to malathion and n-hexane. While resistance to chemical contamination was demonstrated, the ability to degrade the contaminant could not be determined conclusively. Further work can lead to development of efficient bioremediation strategies against these common contaminants . Successful completion of this project can lead to development of efficient bioremediation strategies against these common contaminants.
