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.
