"Although detergents are major environmental pollutants for soil and water, their impact in bacterial community structures has not been addressed. We compared the bacterial community structures as well as several edaphic parameters between severely detergent-contaminated soils and noncontaminated soils in the State of Yucatán, México. The results indicate that sodium concentration, salinity, and electrical conductivity were significantly higher in contaminated samples, and that this correlates with different bacterial community structures. The most important differences were that (i) samples with detergent presented a lower species richness; (ii) Proteobacteria was the most abundant phylum in soils with detergent, while Actinobacteria and Acidobacteria were the most abundant phyla in soils without detergent; (iii) Rhodomicrobium, Hydrogenophaga, and Thiobacillus were the most abundant genera in soils with detergent, while Acidobacteria dominated soils without detergent.
