Metagenomics of Bacterial Consortia for the Bioremediation of Organic Pollutants

Field scale biodegradation of total petroleum hydrocarbons and soil restoration by Ecopiles: microbiological analysis of the process

“…In particular, ex situ approaches are often combined with bioaugmentation, when the pollutant-degrading microorganisms are previously grown and added to carry out the biodegradation process, and with biostimulation, which involves the addition of nutrients and supplements, especially oxygen, nitrogen, and phosphorus into the soil, or modifying the pH or temperature to increase the rates of biodegradation carried out by the native microorganisms (Lin et al, 2010;Tyagi et al, 2011). Both bacterial consortia or isolated strains can be used to implement a bioaugmentation approach (Guirado et al, 2021;Garrido-Sanz et al, 2022), of which the former is thought to be more effective, as it contains a wider variety of bacteria, where very few are specific for a particular contaminant and can act synergically (Varjani, 2017;Garrido-Sanz et al, 2018;Auti et al, 2019;Garrido-Sanz et al, 2019).…”
