Abstract
The microbial activities and the biodegradation-abilities of undefined consortium in contaminated soils in the Niger Delta of Nigeria were studied. The Respirametry technique was adopted to evaluate the microbial activities while the soils were incubated with 2% (υ/υ) crude oil in mineral salt medium at 37°C in three stages of two weeks each in a shake flask. At the end of the last phase, components of the crude oil degraded by the undefined consortium in the soils were identified with the gas chromatographic techniques. The consortia of the different samples studied showed different degree of capacities on the crude oil, removing a large number of components of the crude oil, making the areas potentially suitable for in-situ bioremediation.

Summary
How to cite this paper: Olanipekun, O.O., et al (2015) Comparative Study of Microbial Activities and Biodegradation-Abilities of Undefined Consortium in Some Hydrocarbon Contaminated Sites in the Niger Delta, Nigeria. This has exposed the region to large or repeated oil spills or leaks frequently exhibiting long term environmental problems [1]. Due to the adverse effects of oil (hydrocarbon) contaminants on their environments, the future of the region is being threatened. Bioremediation, which has been established as an efficient, cost-effective and environmentally friendly process, in contrast to the chemical and physical processes of remediating organic compounds contaminated environments, is a system that exploits the ability of some microorganisms to degrade the contaminants. The process depends utmost on the microbial community structure, and thrives on the ability to enrich and maintain microbial populations and activities within the target environment
