The Effect of Cadmium and Chromium Concentration, on Biological Activity of Marsilea minuta

Abstract

Antibacterial activity of the Marsilea minuta was investigated that was collected from four different places of the same stream. The activities were correlated with the chromium and cadmium ions contents of the stream. The concentration of cadmium and chromium was determined by using the atomic absorption spectroscopy. The metal contents were extracted from the plants and crude extract by using wet digestion process. The antibacterial activity was determined by using disc diffusion method. The change in biological activities with the change in concentrations of metal ions is discussed in this communication.
