During 1985, a study was made of the physical, chemical and biological characteristics of the River Guadalquivir. At the same time, the density of certain microorganisms involved in the transformation of sulfur compounds in the water was studied. The results obtained give the following numerical order of density: T. thioparus >sulfate reducers > T. denitrificans > T. thiooxidans. Urban waste was found to increase density levels of these microorganisms. Their relationship with certain environmental parameters is discussed in this study. Regression equations have been obtained of bacteria numbers for three of the four groups studied, using water temperature and permanganate oxidability as dependent variables.
