We speculate that under the conditions used in the present work some indigenous active bacteria presumably present in the soil may have contributed for the formation of these two metabolites during the time-course of the biodegradation experiments. Biol Fertil Soils — Microalgae culturing procedures were as previously outlined [37]. Delmas, J. The main route of chloroacetanilides degradation in soil has been reported to be microbial [26][29][30]. Pick and Choose. View Article Google Scholar 3. Possible deleterious effects exerted by S -MET [2] could contribute to diminish the efficacy of the bioremediation tool previously shown to be effective for the clean-up of soils contaminated with high concentrations of ATZ [14][15][17]. ADP plus citrate Fig.

    Vials non-supplemented with S -MET were included as controls. ADP Rif R viable cells in soil, at each time interval up to 9 days one replicated vial was destructively sampled and processed immediately for the determination of CFU concentration as is described below microbiological analysis. Soil parameters A natural sandy loam soil pH 6.

    Regul Toxicol Pharmacol — More importantly and corroborating previous observations [14]toxicity values were achieved which were comparable to those obtained for eluates from the soil not contaminated with the herbicide Fig.

    Environment Canada Biological test method: growth inhibition test using the freshwater alga Selenastrum capricornutum. The concentrated cell suspension obtained was used as inoculum in survival, mineralization and biodegradation experiments, as is described below. Sci Total Environ — Thus, it appeared that acetochlor represents the highest toxic pressure on periphyton among the other contaminants in the Leyre River.

    Alachlor and metolachlor are dechlorinated and transformed into their corresponding ethane sulfonic acid (ESA) metabolites in soil.

    Triplicate vials were included for each treatment. Combination of soil bioaugmentation with citrate amendment apparently allowed a slight but significant improvement in ATZ removal from the soil, with its concentration decreasing to 0.

    1. As part of a framework for the rational bioremediation of ATZ-contaminated land, we recently presented evidences that a clean-up strategy, combining soil bioaugmentation with this bacterial strain and biostimulation with citrate [17]was effective at a larger microcosms scale [14][15].

    2. Indeed, microalgae growth rates were similar in the eluates from the treated or untreated soils, for both doses of Primextra S-Gold Fig. Pick and Choose.

    3. Herbicides belonging to the chloroacetanilide class have been found in the river S -metolachlor and acetochlor as well as some of their metabolites at higher concentrations.
