Effect of mercury and cadmium on the growth of Anacystis nidulans
- Montclair State College, Upper Montclair, NJ (United States)
Anacystis nidulans is a member of the cyanobacteria, one of the largest and most diverse groups in the prokaryotic kingdom. Cyanobacteria are excellent organisms to serve as models for the investigation of a wide variety of biological problems such as acting as environmental pollution indicators. There have been several studies on the effects of heavy metals on A. nidulans. Some of these elements, such as copper, are known to be essential nutrients for cyanobacteria. Others, like cadmium, are not known to be necessary for normal growth and metabolism. Large amounts of either essential or non-essential elements can be toxic. Toxic metals, such as mercury and cadmium are a major water pollution problem. Metals come from natural weathering processes of the earth's crust, industrial discharge, pest or disease control agents applied to plants, urban run-off, mining, soil erosion, sewage effluents, air pollution fallout and other sources. This study investigates the growth of Anacystis under different concentrations of mercury and cadmium. 13 refs., 2 figs.
