 en Effects of Long-Term Kerosene Spillage on Heterotrophic Microorganisms in Soil from Niger Delta, Southern Nigeria
Nseabasi, N.O. & Antai, S.P.

Abstract

Kerosene contaminated soil was obtained from four different locations in Calabar while pristine soil served as control. Bacterial species isolated from kerosene contaminated soil samples included species of Bacillus check for this species in other resources , Pseudomonas check for this species in other resources , Micrococcus check for this species in other resources and Serratia check for this species in other resources while bacteria isolated from pristine soil samples comprised of species of Streptococcus check for this species in other resources , Salmonella check for this species in other resources , Escherichia coli check for this species in other resources , Staphylococcus aureus check for this species in other resources , Bacillus, Serratia, Micrococcus and Pseudomonas. Similar fungal species which included species of Aspergillus check for this species in other resources , Penicillium check for this species in other resources , Mucor check for this species in other resources , Rhizopus check for this species in other resources , and Fusarium check for this species in other resources were isolated from both chronic kerosene contaminated and pristine soil samples. There was no significant 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 significant difference (p≤0.05) between kerosene utilizing bacteria (KUB) between chronic kerosene contaminated and pristine samples. This revealed that long-term kerosene slippage had a selecting effect on soil bacteria as opposed to soil fungal.
