Clostridium perfringens as a Potential Indicator for the Presence of Sewage Solids in Marine Sediments

摘要

Marine sediment cores collected from several depths of water an distances from a California sewage outfall were tested to see if sediments influenced by sewage solids were a reservoir of enteric pathogens, and if concentrations of indicator bacteria were related to the presence of sewage solids. Vertical distributions of microorganisms in marine sediments were determined; there was a decrease of indi- cator bacteria with increasing sediment depth.
