BIODEGRADATION OF THE ORGANOPHOSPHATE PESTICIDE TETRACHLORVINPHOS BY BACTERIA ISOLATED FROM AGRICULTURAL SOILS IN MÉXICO

A bacterial consortium which degrades tetrachlorvinphos (phosphoric acid, 2-chloro-1-(2,4,5-trichlorophenyl) ethenyl dimethyl ester) was isolated from agricultural soil. This consortium was composed of six pure strains which were characterized based on their morphological and biochemical characteris...

This consortium was composed of six pure strains which were characterized based on their morphological and biochemical characteristics. The strains were presumptively identified as Stenotrophomonas malthophilia, Proteus vulgaris, Vibrio metschinkouii, Serratia ficaria, Serratia spp. and Yersinia enterocolitica. The consortium and the six bacteria were assessed in order to discover their ability to degrade tetrachlorvinphos (TCV) in mineral medium and in rich medium. Growth curve experiments showed that the bacterial consortium was able to grow in mineral medium containing TCV as the only carbon source. However, only one pure strain was able to remove TCV in mineral medium, while all of them removed it in rich medium. Hydrolysis products were detected and identified by gas chromatography-mass spectrometry. These data indicate that the isolated strains can be used for waste biodegradation or bioremediation of TCV-contaminated soil or water.Se aisló un consorcio bacteriano de suelos agrícolas, capaz de degradar tetraclorvinfos (ácido fosfórico, 2-cloro-1-(2,4,5-triclorofenil) etenil dimetil ester). Este consorcio estuvo formado por seis cepas puras que fueron caracterizadas con base en sus características bioquímicas y morfológicas. Las cepas fueron presumiblemente identificadas como Stenotrophomonas malthophilia, Proteus vulgaris, Vibrio metschinkouii, Serratia ficaria, Serratia spp. and Yersinia enterocolitica. El consorcio y las seis cepas puras fueron cultivados en medio mineral y en medio rico, para evaluar su capacidad para degradar TCV. Los resultados de las curvas de crecimiento mostraron que el consorcio es capaz de crecer en presencia de TCV como única fuente de carbono. Sin embargo, sólo una cepa pura removió el TCV del medio de cultivo, pero todas las cepas removieron este plaguicida en medio rico. Los productos de la hidrólisis fueron detectados por cromatografía de gases acoplada a espectrometría de masas. Estos datos indican que las cepas aisladas pueden ser utilizadas para la biodegradación de residuos o para la biorremediación de suelos o aguas contaminadas con este plaguicida.Instituto de Ciencias de la Atmósfera, Universidad Nacional Autónoma de México2010-08-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionARTapplication/pdfhttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/20443Revista Internacional de Contaminación Ambiental; Vol. 26 Núm. 1 (2010); 27-38Revista Internacional de Contaminación Ambiental; Vol. 26 No. 1 (2010); 27-380188-4999reponame:Revista Internacional de Contaminación Ambientalinstname:UNIVERSIDAD NACIONAL AUTÓNOMA DE MÉXICOinstacron:UNAMspahttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/20443/19382Derechos de autor 2017 Revista Internacional de Contaminación Ambientalinfo:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/204432024-08-16T19:00:27Z
