Effect of competition between petroleum-degrading bacteria and indigenous compost microorganisms on the efficiency of petroleum sludge bioremediation: Field application of mineral-based culture in the composting process

The effect of competition between isolated petroleum-degrading bacteria (PDB) and indigenous compost microorganisms (ICM) on the efficiency of composting process in bioremediation of petroleum waste sludge (PWS) was investigated. After isolating two native PDB (Enterobacter hormaechei strain KA6) fr...

After isolating two native PDB (Enterobacter hormaechei strain KA6) from PWS, their ability for growth and crude oil degradation was examined in the mineral-based culture (MBC). Then, the PDB isolate were inoculated into the composting experiments and operated for 12 weeks. The results showed that the PDB degraded 21.65–68.73% of crude oil (1–5%) in the MBC after 7 days. The PDB removed 84.30% of total petroleum hydrocarbon (TPHs) in the composting bioreactor containing the initial TPH level of 20 g kg−1. Removal of petroleum hydrocarbons (PHCs) in the composting experiments proceeded according to the first-order kinetics. The computed values of degradation rate constants and half-lives showed a better performance of the PDB than ICM for TPHs removal. This finding suggests that simultaneous application of the PDB and ICM in the composting reactors resulted in a decline in the effectiveness of the PDB which is due to competition between them. The study also verified that the capability of PDB in degrading PHCs can be successfully scaled-up from MBC to composting process.Se investigó el efecto de la competencia entre las bacterias aisladas que degradan el petróleo (PDB) y los microorganismos autóctonos del compost (ICM) sobre la eficiencia del proceso de compostaje en la biorremediación de lodos residuales de petróleo (PWS). Después de aislar dos PDB nativos (Enterobacter hormaechei cepa KA6) de PWS, se examinó su capacidad de crecimiento y degradación del petróleo crudo en el cultivo de base mineral (MBC). Luego, el aislado de PDB se inoculó en los experimentos de compostaje y se operó durante 12 semanas. Los resultados mostraron que el PDB degradó del 21,65 al 68,73% del petróleo crudo (del 1 al 5%) en el CBM después de 7 días. El AP eliminó el 84,30% del total de hidrocarburos de petróleo (TPH) en el biorreactor de compostaje que contenía el nivel inicial de TPH de 20 g kg-1. La eliminación de hidrocarburos de petróleo (PHC) en los experimentos de compostaje procedió de acuerdo con la cinética de primer orden. Los valores calculados de la tasa de degradaciónLas constantes y las vidas medias mostraron un mejor desempeño del PDB que el ICM para la eliminación de TPH. Este hallazgo sugiere que la aplicación simultánea del AP e ICM en los reactores de compostaje resultó en una disminución en la efectividad del AP debido a la competencia entre ellos. El estudio también verificó que la capacidad del AP para degradar los PHC se puede ampliar con éxito desde el MBC al proceso de compostaje.Elsevier202120212020info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttp://hdl.handle.net/10578/29267reponame:RUIdeRA.
