dc.descriptionEnvironmental pollution is a global problem because of its adverse effects on human beings, plants and animals. Heavy metals are increasingly found in our environment due to natural and industrial process. It has been well reported that microbial interactions with metals may have several implications for the environment such that microbes can be used in the biogeochemical cycling of toxic heavy metals as well as in cleaning up or remediating metal contaminated environments (Badar et al., 2000). Salt et al., (1998) also reported that bacteria tolerance to heavy metals can be used to minimize the effects of heavy metals on total biological activity of the ecosystem. Processes involved in reducing metal toxicity are of considerable current interest particularly for highly contaminated heavy soils.
dc.description.abstractThis study was carried out to establish the relationship between hydrocarbon utilization potential and heavy metal tolerance in bacteria species. Nineteen bacteria species were isolated from soil samples collected from four (4) automobile repair workshops in Ogbomosho, Oyo state Nigeria.The bacteria isolated were identified to be Klebsiella oxytoca(5), Klebsiella edwardsii(13)and Shigella alcalescens(1). Metal tolerance assay revealed that Klebsiella oxytoca, Klebsiella edwardsii and Shigella alcalescens have the ability to grow in the presence of Zncl2, Pbcl2 and CuSO4. The minimum inhibitory concentration (MIC) of the metal salts ranged from 1mM to >16mM for Pbcl2, 2mM to >16mM for Zncl2 and 8mM to >24 for CuSO4. The ability of the bacteria strains to utilize hydrocarbons was also investigated by measuring the optical density of the strains in minimal salt mediumsupplemented crude oil at 625nm. The results showed that there is relationship between hydrocarbon utilization and heavy metal tolerance among the bacteria. Keywords:
