Bioaugmentation with a fungal-bacterial consortium and biostimulation of native microbiota using corn stover as texturizer produced appreciable changes in the microbial diversity of polluted soils, shifting native microbial communities in favor of degrading specific populations. Functional metagenomics showed changes in gene abundance suggesting a bias towards aromatic hydrocarbon and intermediary degradation pathways, which greatly favored PAH mineralization. In contrast, pathways favoring the formation of toxic intermediates such as cytochrome P450-mediated reactions were found to be significantly reduced in bioaugmented soils. PAH biodegradation in soil using the microbial consortium was faster and reached higher degradation values (84% after 30 d) as a result of an increased co-metabolic degradation when compared with other mixed microbial consortia. The main differences between inoculated and non-inoculated soils were observed in aromatic ring-hydroxylating dioxygenases, laccase, protocatechuate, salicylate and benzoate-degrading enzyme genes. Based on our results, we propose that several concurrent metabolic pathways are taking place in soils during PAH degradation.application/pdf10.1016/j.jhazmat.2016.07.0600304-3894https://repositorio.udes.edu.co/handle/001/3447engJournal of Hazardous MaterialsDerechos Reservados - Elsevier, 2016info:eu-repo/semantics/openAccessAtribución-NoComercial 4.0 Internacional (CC BY-NC 4.0)https://creativecommons.org/licenses/by-nc/4.0/http://purl.org/coar/access_right/c_abf2https://www.sciencedirect.com/science/article/pii/S0304389416306926?via%3Dihub#!Polycyclic aromatic hydrocarbons (PAHs)MetagenomicsSoil bioremediationAromatic-ring-hydroxylating dioxygenasesMicrobial consortiumComparative metagenomic analysis of PAH degradation in soil by a mixed microbial consortiumArtículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Textinfo:eu-repo/semantics/articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a85PublicationTEXTComparative metagenomic analysis of PAH degradation in soil by a mixed microbial consortium.pdf.txtComparative metagenomic analysis of PAH degradation in soil by a mixed microbial consortium.pdf.txtExtracted texttext/plain2https://repositorio.udes.edu.co/bitstreams/4a4f6b29-149d-4f49-a065-52a5319b6a97/downloadd784fa8b6d98d27699781bd9a7cf19f0MD56ORIGINALComparative metagenomic analysis of PAH degradation in soil by a mixed microbial consortium.pdfComparative metagenomic analysis of PAH degradation in soil by a mixed microbial consortium.pdfapplication/pdf235215https://repositorio.udes.edu.co/bitstreams/11cee882-87d7-4522-8ea9-2075c9a7ac11/downloadcf4392f39f258a26102d8a01c9e3ece4MD55BRANDED_PREVIEWComparative metagenomic analysis of PAH degradation in soil by a mixed microbial consortium.PNG.preview.jpgComparative metagenomic analysis of PAH degradation in soil by a mixed microbial consortium.PNG.preview.jpgGenerated Branded Previewimage/jpeg5760https://repositorio.udes.edu.co/bitstreams/1ab9ea89-62b4-4e0d-8f4c-40d60864ddff/downloadd36515ec382bc2c5cd09d40055c31c7eMD54THUMBNAILComparative metagenomic analysis of PAH degradation in soil by a mixed microbial consortium.PNG.jpgComparative metagenomic analysis of PAH degradation in soil by a mixed microbial consortium.PNG.jpgUDESimage/jpeg1494https://repositorio.udes.edu.co/bitstreams/85c1bef1-6ca3-4a01-91fe-02e2d91b052e/download232522f87e9974d93f962b07115ee47cMD53Comparative metagenomic analysis of PAH degradation in soil by a mixed microbial consortium.pdf.jpgComparative metagenomic analysis of PAH degradation in soil by a mixed microbial consortium.pdf.jpgGenerated Thumbnailimage/jpeg1550https://repositorio.udes.edu.co/bitstreams/b5ec006d-1120-4740-a27c-96cd65d7c91c/download4258c52672af783a5534c8ca75d035e7MD57LICENSElicense.txtlicense.txttext/plain; charset=utf-859https://repositorio.udes.edu.co/bitstreams/130bcf1f-f837-4714-a47f-b4f54f318753/download38d94cf55aa1bf2dac1a736ac45c881cMD52001/3447oai:repositorio.udes.edu.co:001/34472023-10-11 10:18:08.734https://creativecommons.org/licenses/by-nc/4.0/Derechos Reservados - Elsevier, 2016https://repositorio.udes.edu.coRepositorio Universidad de Santandersoporte@metabiblioteca.comTGljZW5jaWEgZGUgUHVibGljYWNpw7NuIFVERVMKRGlyZWN0cmljZXMgZGUgVVNPIHkgQUNDRVNPCgo= |
