Abstract
Survival of six bacterial species with different growth rates was tested in raw sewage and sewage rendered free of protozoa. When the six species were inoculated at the same densities into sewage containing protozoa, the three slow-growing species were rapidly eliminated, and two of the three fast-growing species survived in detectable numbers. It is suggested that in environments with intense protozoan predation, protozoa may alter composition of bacterial communities by eliminating slow-growing bacteria.
