Biodegradability of hydrocarbons in the refinery wastewater from moustorod oil refinery

The present investigation deals with the study of hydrocarbon degradation present in refinery wastewater by natural microbial flora in addition to that obtained using Ps. aeruginosa under laboratory conditions. Results indicated that Ps. aeruginosa may have a significant role in the degradation of hydrocarbons. After seven days, several of the compounds in the original wastewater were completely degraded and four compounds (n-paraffins) were partially degraded. Without Ps. aerruginosa, the same picture had been obtained after 23 days.
