Development of microbial biosorbents - a need for standardization of experimental protocols

摘要

An exhaustive culture isolation and screening program was undertaken in laboratory to obtain highly effiicent metal sorbing microorganisms.the isolates belonged to diverse groups viz.i) Gram positive bacteria,ii) Gram negative bacteria, iii) yeasts,iv) fungi and v) algae.It was found that all the microbial cultures tested possessed ability to adsorb metals like lead,cadmium,chromium,copper,zinc and silver from solutions.Bacteria and algae showed higher metal uptake than fungi and yeasts.
