Detergents are a pollutant agent which can be found frequently in agricultural soils. There are numerous channels for the passing of chemical components to the soils. Two primary ways are the use of distilled water (both of domestic and industrial origin), and of fertilizers based out of biological mixtures. A study done by the Institute of Water and the Department of Microbiology at the University of Granada, directed by Dr. Maria del Mar Snchez Peinado , stress the importance of controlling the contamination of our farm grounds. This is due to the increasing presence of linear alkyl benzene sulphonate, a chemical component whose active ingredient can be found in most detergents.
The research project, carried out by three professors, Clementina Pozo Llorente, Maria Beln Rodelas Gonzlez, and Maria Victoria Martnez Toledo, was financed by the Ministry of Education. This study has proven to be an important advancement towards further understanding of agricultural soils as a receptor of these pollutant compounds, as well as the impact of such compounds on the microbial community, and its microbiotic role on agricultural soils with regards to LAS biodegradation processes. The field work of this study was conducted in the lowlands of Spain, researching LAS biotransformation capacity with regards to microbiota as well as its biotransformation kinetics.

At this moment LAS is the most used anionic surfactant in the worldwide detergent market. Its international consumption reaches values of 2,000 kt per year and by the year 2010 it is expected to reach values of up to 3,400 kt per year. However, the UGR scientis
