- Abstract
This article cites a study on bioluminescent bacteria as indicators of chemical contamination of coastal waters. The ratio of bioluminescent to total bacteria as an indicator of a variety of types of anthropogenic contamination of estuarine ecosystems was evaluated through a series of laboratory and field studies. Laboratory studies indicated that the bioluminescent ratio of natural bacterioplankton communities was proportionally reduced in the presence of a number of contaminants including diesel fuel and salt-marsh sediments co-contaminated with mercury and polychlorinated biphenyls. Bioluminescent ratio inhibition was observed after short-term exposure to a contaminant suggesting a physiological rather than a population response of native microbial communities. Although the BLR was not significantly correlated to salinity at a single site, the BLR was significantly correlated with salinity when sites within the same estuary system were compared. Variation in BLR was not correlated to standard bacteriological indicators of water quality including total and fecal coliform bacteria.
