Description

Bioremediation technology comes of age due to frequent occurrence of oil pollution accidents which have caused ecological and social catastrophe. The aims of the project were to isolate the potential hydrocarbon-degrading bacteria and to study a biodegradation potential of the selected bacteria in a flask system, bioreactor system and application of bacterial inoculum in the Tapis crude oil-contaminated soil. One of the bacterial isolate, namely Acinetobacter baumannii T30C was screened as potential hydrocarbons degrader. The sustainability growth of the bacteria isolate Acinetobacter baumannii T30C was tested, which bacteria was augmented in Tapis crude oil-contaminated soil. Analysis of gas chromatography-flame ionization detection (GC-FID) showed that most aliphatic hydrocarbons (n-alkanes) were degraded extensively by bacterial isolate Acinetobacter baumannii T30C. This work gave a contribution in terms of understanding the occurrence of oil biodegradation in tropical soils, in which the addition of inoculum of microbial degraders (bioaugmentation) and nutrients (biostimulation) is especially relevant.
