Protein Profile Changes in Chrococcus dispersus, Microcystis flos-aquae and Microcoleus steenstruqii in Response to Cadmium Treatments

The electrophoretic studies were carried out on threeselected algal species, namely Chrococcus dispersus, Microcystis flosaquaeand Microcoleus steenstruqii exposed to two differentconcentrations (low = 0.5 high = 2 ppm) of cadmium. Protein profileanalyzed by SDS PAGE gel electrophoresis showed differentialexpression of several proteins. Considerable changes in the numberand the percentages of protein fractions are found for each alga. Inaddition, each organism reacts so differently and individually inresponse to heavy metal exposure.
