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