Chemical compound present in detergents produce bacteria alterations in agricultural soils
Date:11/8/2007

ts believe that its high global production, the need to use it and the toxicity of its initial forms and of some of its waste products determine the need to control it in different environmental circumstances.

This research work goes deeply, from chemical, microbiological and molecular techniques, into the impact of LAS in the structure, function and composition of the microbial community in the soil ecosystem. Likewise, the scientists have analyzed the biodegradation capacity of this pollutant in fields with regards to the microbial community combining techniques corresponding to different knowledge areas, such as microbiology, analytical chemistry and microbiology.

With regards to agricultural soils, the use of biological mud as a fertilizer and the great demand for water due to agricultural needs are the main means ways that LAS reaches the fields. A unique ecosystem, where biological interactions and biogeochemical processes, associated to organic material degradation and mineral elements transformation for plant nutrition are especially intense.

The scientists of the University of Granada warn about the negative effects of LAS LAS could significantly alter the metabolic activity of soils, therefore affecting their fertility.
