Bioreactors for remediation of hydrocarbons in rivers and lagoons of San Luis Potosí

Abstract

totales del petróleo intemperizados en suelos y sedimentos (Biodegradation modeling of sludge bioreactors of total petroleum hydrocarbons weathering in soil and sediments)

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

“…This contamination is caused by leaks, accidental spills, and anthropogenic activities (Zhang et al, 2019;Sonwani et al, 2020;Tao et al, 2020). Activities related to tourism, commercial transport, industries, and the inadequate disposal of residues are some examples of the principal sources of water contamination (Almeida et al, 2019;Ostendorf et al, 2019;Sandoval-Herazo et al, 2020;Ray et al, 2021). In some cases, the neglected disposal of waste oils by people can worsen the problem (Su et al, 2011;Naima and Liazid, 2013;Almeida et al, 2019;Ostendorf et al, 2019).…”

“…The biodegradation potential of crude petroleum has been assessed by hydrocarbonoclastic bacteria isolated from Soummam wadi sediments (Yalaoui-Guellal et al, 2020). The hexadecane uptake has been identified using an oil-degrader consortium (Hernández-Martínez et al, 2019;Sandoval-Herazo et al, 2020), and the evaluation of the ability to degrade crude and fuel oil has been determined by a native microbial consortium (NMC) (Canul-Chan et al, 2018;Rani et al, 2020). Besides, the enhancement of microorganism potential to degrade petroleum hydrocarbons can be improved using bioreactors, such as packed-bed bioreactors (PBBRs) operated in continuous mode (Kureel et al, 2018;Sonwani et al, 2020), fluidized bed bioreactors (Kuyukina et al, 2017), inverse fluidized bed bioreactors (Mallikarjuna and Dash, 2020), and a PBBR (Hussain et al, 2015;Kumar et al, 2015;Berrelleza-Valdez et al, 2019).…”
