Response of Natural Marine Bacterial Populations to Copper: Controlled Ecosystem Pollution Experiment
Abstract:The addition of Cu2+ at 10 and 50 μg/l to two enclosed marine ecosystems led to a marked increase in the relative numbers and activity of bacterial heterotrophs. This acceleration appears to follow the release of available organic carbon from one or more copper-sensitive components of the original ecosystem. Ultimately, the bacterial survivors, which demonstrate an increased tolerance to copper with time, reciprocate by providing a source of plant nutrients suitable for the establishment of succeeding phytoplankton regimes.
