Phytoremediation is an alternative for cleaning contaminated soils using plants and associative microorganisms. This study evaluated the phytotoxicity and phytoremediation of a gasoline-contaminated soil by sunflower plants (Helianthus annuus L.) assisted with native rhizosphere bacteria. The research consisted of three experimental phases based on artificially gasoline-contaminated soil. The first phase evaluated the seed germination and seedling emergence under contaminated soil (0, 200, 400, 800, 1600, 2400, and 3200 mg/kg); for 20 days, seed germination and seedling tolerance were achieved at all concentrations. The second phase of the study isolated bacteria from the contaminated soil, characterized by biochemical tests related to plant growth promotion, and molecularly identified. Gasoline inhibited bacterial growth, and ten potential plant growth-promoting bacteria were isolated, which belonged to Bacillus, Streptomyces, Pseudomonas, Priestia, Massilia, and Sphingobium. The third phase consisted of a bioassay for phytoremediation of gasoline-contaminated soil (0, 1600, and 3200 mg/kg) by inoculating sunflower plants with the ten bacteria obtained from phase 2 as a bacterial consortium. After 60 days, despite not having influenced plant growth, bacterial inoculation significantly diminished the soil contaminant (~50 % removal). The inoculation of the sunflower plants with ten native bacteria reduced the gasoline-contamination in soil. |

El presente trabajo evaluó la fitotoxicidad y la fitorremediación de un suelo contaminado con gasolina por plantas de girasol (Helianthus annuus L.) asistida con bacterias rizosféricas nativas. Esta investigación contempló tres fases experimentales partiendo de un suelo artificialmente contaminado con gasolina. La primera fase evaluó la germinación de semillas de girasol y su crecimiento en un suelo contaminado (0, 200, 400, 800, 1600, 2400 y 3200 mg/kg), observándose la germinación y la tolerancia de las plántulas en todas las concentraciones de gasolina, a los 20 días. En la segunda fase se aislaron bacterias totales del suelo contaminado y se caracterizaron mediante pruebas bioquímicas relacionadas con el crecimiento vegetal y se identificaron molecularmente. La gasolina inhibió el crecimiento bacteriano, y se seleccionaron 10 cepas con capacidad promotora del crecimiento vegetal, sobresaliendo los géneros Bacillus, Streptomyces, Pseudomonas, Priestia, Massilia y Sphingobium. La tercera fase consistió en un bioensayo de fitorremediación del suelo contaminado (0, 1600 y 3200 mg/kg) inoculando plantas con las 10 bacterias aisladas de la fase 2, aplicadas en consorcio. A los 60 días, a pesar de no influir en el crecimiento vegetal, las bacterias disminuyeron significativamente la presencia del contaminante en el suelo (~50 % remoción). La inoculación de girasol con bacterias nativas es una alternativa para reducir la contaminación de gasolina en el suelo.Instituto de Ciencias de la Atmósfera, Universidad Nacional Autónoma de México2024-07-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionARTTextotext/htmlapplication/pdfhttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/5503910.20937/RICA.55039Revista Internacional de Contaminación Ambiental; Vol. 40 (2024); 351-362Revista Internacional de Contaminación Ambiental; Vol. 40 (2024); 351-3620188-4999reponame:Revista Internacional de Contaminación Ambientalinstname:UNIVERSIDAD NACIONAL AUTÓNOMA DE MÉXICOinstacron:UNAMspahttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/55039/47428https://www.revistascca.unam.mx/rica/index.php/rica/article/view/55039/47426Derechos de autor 2024 Revista Internacional de Contaminación Ambientalhttps://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/550392024-08-16T19:00:42Z |
