Degradación del clorotalonilo por un consorcio microbiano aislado de humedales construidos en ensayos de laboratorio

ABSTRACT: In the laboratory, we evaluated Chlotothalonil degradation by a microbial consortium isolated from the biofilm formed on the gravel of wetlands constructed with a horizontal subsurface flow for treatment of agricultural wastewater, and we estimated the effect of the pesticide on the growth dynamics of the total heterotrophic community and the population of Pseudomonas spp. A chlorothalonil concentration (CLT) of 0,6 mg l-1 and two levels of dissolved organic carbon concentration (COD) of 20 and 100 mg l-1 (employing glucose as a carbon source) were used in the experiments conducted in a solution of synthetic waste water. The response variables were: residual CLT concentration, residual COD concentration, and counts of colony forming units (CFU) of heterotrophic bacteria and Pseudomonas spp. The control variables measured during the process to determine changes in the physicochemical conditions were: electrical conductivity, dissolved oxygen, pH, and redox potential. It was shown that the level of organic carbon concentration notably affected CLT degradation. With 100 mg l-1 of COD, a 99.7% degradation of CLT was attained after 168 h of trial; while 45.1% was attained with 20 mg l-1 of COD. In the chromatographic analysis no degradation products were detected. |

Las variables respuesta fueron: concentración residual de CLT, concentración residual de COD, y recuento de unidades formadoras de colonias (UFC) de las poblaciones de HT y Pseudomonas spp. Las variables control que se midieron durante el proceso para determinar cambios en las condiciones sicoquímicas del medio, fueron: conductividad eléctrica, oxígeno disuelto, pH y potencial redox. Se comprobó que el nivel de concentración de carbono orgánico afectó notablemente la degradación del CLT. Con 100 mg l-1 de COD se alcanzó 99,7% de degradación de CLT a las 168 horas del ensayo; en tanto que 45,1%, se alcanzó con 20 mg l-1 de COD. En el análisis cromatográ co no se detectaron productos de degradación.application/pdfspaUniversidad de Antioquia, Facultad de Ciencias Exactas y Naturales, Instituto de BiologíaMedellín, Colombiahttps://creativecommons.org/licenses/by-nc-sa/2.5/co/https://creativecommons.org/licenses/by-nc-sa/4.0/Atribución-NoComercial-CompartirIgual 2.5 Colombia (CC BY-NC-SA 2.5 CO)info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Degradación del clorotalonilo por un consorcio microbiano aislado de humedales construidos en ensayos de laboratorioChlorothalonil degradation by a microbial consortium isolated from constructed wetlands in laboratory trialsArtículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionHumedales construidosWetlands, ConstructedCarbono orgánicoOrganic carbonDegradaciónDegradationClorotaloniloConsorcio microbianohttp://aims.fao.org/aos/agrovoc/c_2f82b0a2http://aims.fao.org/aos/agrovoc/c_2159Actual.
