Das K. and Adak M.K., 2015, Biosorption Property of Cadmium (II) in Marsilea minuta L. with Polyamine Interaction, Molecular Plant Breeding, 6(14): 1-4 (doi: 10.5376/mpb.2015.06.0014)

A study was undertaken for biosorption following bio accumulation property of Marsilea minuta L., an aquatic pteridophyte in cadmium enriched solutions. The possible mechanism for biosorption on the cell wall residues has been discussed with exogenous applications of polyamine. Initially plants were evaluated both with fresh and dry mass for their differential adsorption. A typical distribution of metal in different tissues, more into cortical and endodermal apoplastic regions were the features as detected by Energy Dispersive Analysis of X-ray study. The changes of the cell wall residues and their possible interaction with metals have been analyzed with Fourier Transform Infrared Spectrometric studies. With this study the most possible contributing chemical bond was detected as alkyl halide with its possible changes in energy absorption. This was also minimized by spermidine application and thus established its involvement for biosorption of metal. Accumulation of Cd in relation to chemical mechanism has been discussed in Marsilea and analyzed its efficacy as a well hyper-accumulator under metal contaminated environment.
