ACUNA, Adrian J; CAMBARIERI, Luciana e PUCCI, Graciela Ν.. Biodegradation of two residues from service stations in Río Gallegos - Argentina. Acta biol.Colomb. [online]. 2020, vol.25, n.3, pp.299-309. Epub 28-Dez-2020. ISSN 0120-548X. https://doi.org/10.15446/abc.v25n3.77690.
Gasoline station leached is an inconvenient to control and give a treatment of this waste. The aim of this work was to study the bioremediation of waste from gasoline stations in the city of Río Gallegos. The characterization of the oil phase was carried out and bioremediation was performed with microcosm thereof, the follow-up was performed with the GC-MS for hydrocarbons and fatty acid profiles, and the hydrocarbon degrading bacteria were also monitored. The content of the profile was different from the chromatographic profile; the impact on the degradation of the same that was used for residue 1 was 79.68% and for residue 2, it was 29.23%. The second one is a profile richer in light weight hydrocarbons that are toxic to bacteria. The impact on the microbiota was due to the composition of the waste. Based on the Shanon index, there is a predominance of gram positive bacteria. The non-aqueous liquid phase obtained from the effluents can be bioremediated by the bacterial soil community.
