| Abstract: | Biodegradation of diesel in the presence of mixed microorganism consortium was studied by gas chromatography and ultraviolet spectrophotometry in aqueous solutions. It is shown that the combination of the two simple analytical techniques remedies the shortage of the single one, and that the combination is successfully used to monitor the biodegradation efficiency of diesel and its primary components, and to evaluate separately the degradation of linear alkanes and aromatic hydrocarbons components. The experimental results further demonstrate that the mixed microorganism consortium can degrade diesel in aqueous solutions efficiently, achieving a removal of about 80% over five days. |
