DDT in sediments from the northwest coast of Baja California (Mexico) and its biotransformation by Vibrio sp.

During December 2003, sediment samples were collected at 20 stations along the northwest coast of Baja California (Mexico). Analyses of DDT were performed by gas chromatography, percentage of particles <63 μm in diameter, organic carbon, and sulphate-reducing bacteria. A bacterium from statio...

Analyses of DDT were performed by gas chromatography, percentage of particles <63 μm in diameter, organic carbon, and sulphate-reducing bacteria. A bacterium from station 49, which showed the highest concentration of DDT and its metabolites DDE and DDD, was isolated and identified biochemically and molecularly to belong to the genus Vibrio. In the laboratory this bacterium was tested in minimal salts medium plus DDT and incubated at 28ºC under aerobic and anaerobic conditions for 90 days. In general, the sediments showed low concentrations of DDT, ranging from undetected to 4.78 ng g–1, and the highest concentrations occurred at the deepest stations containing higher percentages of particles <63 μm and organic carbon concentrations. The isolated Vibrio strain showed an ability to biotransform DDT under aerobic and anaerobic conditions, presenting the o,p′-DDE and o,p′-DDD metabolites after 60 and 90 days of incubation in both conditions. Durante diciembre de 2003 se colectaron muestras de sedimento superficial en 20 estaciones de la costa noroccidental de Baja California (México). Se realizaron análisis de DDT por cromatografía de gases, porcentaje de partículas 63 μm de diámetro, carbono orgánico y bacterias reductoras de sulfato. De la estación 49, la cual mostró la mayor concentración de DDT y sus metabolitos DDE y DDD, se aisló una bacteria identificada bioquímica y molecularmente como del género Vibrio, misma que fue sometida a un bioensayo en el laboratorio, en medio de sales mínimas más DDT, e incubada a 28ºC bajo condiciones aerobias y anaerobias durante 90 días. En general, los sedimentos mostraron bajas concentraciones de DDT, desde indetectables hasta 4.78 ng g–1, con tendencia a aumentar en las estaciones más profundas, las cuales contienen mayor porcentaje de partículas <63 μm y concentración de carbono orgánico. La cepa aislada mostró en el laboratorio la capacidad de biotransformar el DDT, detectándose la presencia de los metabolitos o,p′-DDE y o,p′-DDD a los 60 y 90 días de incubación en ambas condiciones.Iniversidad Autónoma de Baja California2008-11-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Article Artículo Arbitradoapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/123110.7773/cm.v34i4.1231Ciencias Marinas; Vol. 34 No. 4 (2008); 419-432Ciencias Marinas; Vol. 34 Núm. 4 (2008); 419-4322395-90530185-3880reponame:Ciencias Marinasinstname:UNIVERSIDAD AUTÓNOMA DE BAJA CALIFORNIAinstacron:UABCenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1231/1817info:eu-repo/semantics/openAccessoai:cienciasmarinas.com.mx:article/12312024-08-22T17:01:38Z
