Contenido motor oil wastewater treatment in a packed bed bioreactor using immobilized native microbial consortium

Abstract

The global increase in population has led to a higher demand for motor oil from a raising number of automobiles. The inappropriate disposal of wasteintemperizadosmotor oilengeneratessuelos y watersedimentoscontamination, therefore, removing motor oil from contaminated water can prevent damage to the environment and human health. In this study, a new native microbial consortium from contaminated soil was tested and exposed to(Biodegradationdifferent concentrationsmodeling of motorsludge oil.bioreactorsThe kineticof totalanalysispetroleumrevealedhydrocarbonsthat the maximumweatheringspecificin soil growth rate was 0.758 d−1, whileandthe sediments) saturation and inhibition constants were 7.11 and 23.77 mg mL−1, respectively. The consortium was immobilized over a plastic packing and employed in studies of motor oil degradation using a packed bed bioreactor. The S.A. Medina-Moreno, S. Huerta-Ochoa, C.A.
