摘要

Kerosene contaminated soil was obtained from four different locations in Calabar while pristinesoil served as control. Bacterial species isolated from kerosene contaminated soil samples included species of Bacillus , Pseudomonas , Micrococcus and Serratia while bacteria isolated from pristine soil samples comprised ofspecies of Streptococcus , Salmonella , Escherichia coli , Staphylococcus aureus , Bacillus, Serratia, Micrococcusand Pseudomonas. Similar fungal species which included species of Aspergillus , Penicillium , Mucor , Rhizopus ,and Fusarium were isolated from both chronic kerosene contaminated and pristine soil samples. There was nosignificant difference (p≥0.05) in heterotrophic bacteria (HTB), fungal (HTF) and kerosene utilizing fungal counts(KUF) between chronic kerosene contaminated and pristine soil samples. However, there was significantdifference (p≤0.05) between kerosene utilizing bacteria (KUB) between chronic kerosene contaminated andpristine samples. This revealed that long-term kerosene slippage had a selecting effect on soil bacteria as opposedto soil fungal.
