Abstract
Description
In this study, we investigated the use of indigenous bacterial species from
contaminated site to degrade kerosene. The method of continual enrichment on
kerosene, yielded bacterial isolates with potential of utilizing kerosene as growth
substrates. The time course studies monitored by the optical density (OD) and pH fluxes
of the pure cultures in varying concentrations of kerosene resulted in exponential
increase in cell numbers and decline in the pH values. From the morphological and
biochemical characterization and comparison with respect to the standard references,
the isolates were presumably the members of the genera Rhodococcus Bacillus and
Aerobacter species. All the strains readily utilized the kerosene as sole sources of
carbon and energy.
