MODERN APPROACHES FOR THE STUDY OF s-TRIAZINE HERBICIDE BIOREMEDIATION IN AGRICULTURAL SOILS R.C. Suelo Nutr. Veg.
Hernández,Marcela; Morgante,Verónica; Flores,Cecilia; Villalobos,Patricio; González,Myriam; Miralles,Pola; Dinamarca,Alejandro; Seeger,Michael.
The extensive use of s-triazine herbicides in diverse countries causes environmental and health concern. Simazine and atrazine are s-triazines widely used in agriculture and forestry. Although, natural dissipation of s-triazines in soils by physicochemical processes has been described, the main mechanism for their removal is biological degradation by microorganisms. Bioremediation is a successful strategy for the removal of i-triazines in soil. For bioaugmentation processes, s-triazine-degrading bacteria are required, which isolation from agricultural soils was described in this report. Studies of s-triazine adsorption and leaching in soil are useful to determine the bioavailability of these herbicides. The detection of s-triazine-degrading catabolic...

Novel s-triazine-degrading bacteria isolated from agricultural soils of central Chile for herbicide bioremediation Electron. J. Biotechnol.
Hernández García,Marcela; Morgante,Verónica; Ávila Perez,Marcela; Villalobos Biaggini,Patricio; Miralles Noé,Pola; González Vergara,Myriam; Seeger Pfeiffer,Michael.
s-Triazine-degrading bacterial strains were isolated from long-term simazine-treated agricultural soils of central Chile. The number of culturable heterotrophic bacteria of these agricultural soils (7 x 10(6) CFU/g of dry soil) was not affected by simazine application on field. The simazine-degrading bacterial strains P51, P52 and C53 were isolated by enrichment in minimal medium using simazine as the sole nitrogen source. Resting cells of strains P51 and P52 degraded >80% of simazine within 48 hrs, whereas strain C53 was able to remove >60% of the herbicide. The atzA and atzD genes of the s-triazine upper and lower catabolic pathways were detected in strains P51 and C53, while only atzD gene was observed in strain P52. To compare the bacterial 16S...

Toxicité d'un désherbant, l'atrazine-simazine, sur les jeunes stades larvaires de Crassostrea gigas et sur deux algues fourrages, Isochrysis aff-galbana et Chaestoceros calcitrans ArchiMer
Robert, Rene; His, Edouard; Maurer, Daniele.
Corn culture has strongly developed in Aquitaine (France) over the past years, and lead to an increased use of pesticides and herbicides. One of the most commonly used formulations around the coast of the Arcachon Bay, an historical oyster spat capture zone, is the Atrazine-Simazine mix. The action limits of this product are defined on Crassostrea gigas larvae and on two nanoplankton test strains used in a controlled environment for their food, Isochrysis aff-galbana and Chaetoceros calcitrans. Herbicides can indeed directly impact on oyster larvae, but they can also have a negative impact by interfering with the development of the algae used as aquaculture feed and feed for veligeres.
Tipo: Text Palavras-chave: Chaestoceros calcitrans; Isochrysis aff galbana; Algues unicellulaires; Crassostrea gigas; LARVES; Simazine; Atrazine; Ecotoxicologie.
