Impact of Metazooplankton Filter Feeding on Escherichia coli under Variable Environmental Conditions.

The fecal indicator bacterial species is an important measure of water quality and a leading cause of impaired surface waters. We investigated the impact of the filter-feeding metazooplankton on the inactivation of The clearance rates of these daphnids were calculated from a series of batch experiments conducted under variable environmental conditions. Batch system experiments of 24 to 48 h in duration were completed to test the impacts of bacterial concentration, organism density, temperature, and water type.
