THE DIVERSITY OF HETEROTROPHIC BACTERIAL MICROFLORA IN SOIL POLLUTED WITH CRUDE OIL AND DIFFERENT TREATMENTS
Petroleum hydrocarbon pollution is one of the main environmental problems, not only bythe important amounts released but also because of their toxicity. It is known that the mainmicroorganisms consuming petroleum hydrocarbons are bacteria. The present researchwork reports the diversity of microrganis from crude oil polluted soil been treated with anatural biodegradable product and bacterial inoculum. The bacterial inoculum was used toenrich indigenous microbes to enhance biodegradation rate. In soil excessively polluted with crude oil, bacterial population size in conditioned variant with Ecosol maximum dose (1%) presented values comparable to those of inoculated variants, demonstrating the protective and stimulation effect of soil bacteria, including those involved in the degradation of petroleum hydrocarbons exercised by organic compound applied Ecosol.
