Interaction of atrazine with soil microorganisms: population changes and accumulation.

摘要: A loam soil treated with atrazine at rates of 10, 30, and 100 μg/g resulted in increased populations actinomycetes, bacteria, fungi over those non-treated soil. The increases were proportion to the amount persisted for least 2 months. Living actinomycete fungal mycelia incubated 48 h distilled water, nutrient broth, or containing 5 μg/ml (g) herbicide. Actinomycete accumulated from water concentrations up 87-fold 132-fold, respectively, that ambient medium. maximum accumulation by was 26-fold 13-fold. Fungi little no a medium whereas actinomycetes Dead usually did not accumulate excess concentration. Mycelium Sclerotium rolfsii growing 20 μg atrazine/ml 157 μg/g wet weight after 8 days. Scler...
