Biodegradation of low density polyethylene by the action of a microbial consortium isolated from a landfill, Lima, Peru
Descripción del Articulo
In this paper, we describe the isolation and biodegradation activity of microorganisms on low density polyethylene. The microorganisms were collected from plastic materials with evidence of deterioration from a landfill. The samples were filtered and selected in a mineral salts medium at pH 5.5 and...

Biodegradation of low density polyethylene by the action of a microbial consortium isolated from a landfill, Lima, PeruBiodegradación de polietileno de baja densidad por acción de un consorcio microbiano aislado de un relleno sanitario, Lima, PerúUribe, DiegoGiraldo, DanielGutiérrez, SusanaMerino, FernandoSpectroscopyPolyethylenePlasticsBiodegradationPolymers.EspectroscopiaPolietilenoPlásticosBiodegradaciónPolímeros.In this paper, we describe the isolation and biodegradation activity of microorganisms on low density polyethylene. The microorganisms were collected from plastic materials with evidence of deterioration from a landfill. The samples were filtered and selected in a mineral salts medium at pH 5.5 and 7 for bacteria and fungi respectively. Six strains were isolated, identified as Pseudomonas sp. Hyalodendron sp., Penicillium sp. and Rhodotorula sp. Microbial activity was evidenced by changes in the infrared spectrum of polyethylene with respect to the polymer without treatment. Reduction of carbonyl index (83.89% at pH 7 and 4.08% at pH 5.5) and double bonds index (19.77% at pH 7 and 6.47% at pH 5.5) were observed. Finally we determined the percentage of weight lost by the polyethylene subjected to activity of the strains, with a decrease of 5.4% at pH 7 and 4.8% at pH5, 5.En el presente trabajo describimos el aislamiento y la actividad de biodegradación de microorganismos sobre polietileno de baja densidad. Los microorganismos fueron aislados de materiales plásticos con evidencias de deterioro procedentes de un relleno sanitario de Lima. Las muestras fueron filtradas y preseleccionadas en medio de sales minerales a pH 5,5 y 7, para hongos y bacterias respectivamente. Se aislaron 6 cepas, identificadas como Pseudomonas sp. MP3a y MP3b, Penicillium sp. MP3a, Rhodotorula sp. MP3b, Hyalodendron sp. MP3c y una levadura no identificada. La acción degradativa del consorcio microbiano aislado fue evidenciada por variaciones en el espectro infrarrojo del polietileno con respecto al polímero sin tratamiento, observándose la reducción del índice de carbonilo (83,89% a pH 7 y 4,08% a pH 5,5) y de terminaciones con dobles enlaces (19,77% a pH 7 y 6,47% a pH 5,5). Finalmente se determinó el porcentaje de peso perdido por el polietileno sometido a las cepas aisladas, observándose una disminución de 5,4% a pH 7 y 4,8% a pH5,5.Universidad Nacional Mayor de San Marcos, Facultad de Ciencias Biológicas2010-04-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/rpb/article/view/6210.15381/rpb.v17i1.62Revista Peruana de Biología; Vol. 17 Núm. 1 (2010); 133 - 136Revista Peruana de Biología; Vol. 17 No. 1 (2010); 133 - 1361727-99331561-0837reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/rpb/article/view/62/57Derechos de autor 2010 Diego Uribe, Daniel Giraldo, Susana Gutiérrez, Fernando Merinohttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/622020-05-21T18:08:23Z |
