The Langmuir and. The dead biomass of Bacillus subtilis has been used for the removal of lead (II) from an aqueous solution. The effects of various parameters such as contact time, adsorbate concentration, pH of the medium and temperature were examined. Optimum removal at 20 0C was found to be % at pH , with an initial Pb (II) concentration of mgL
microbial biomass like Corynebacterium glutamicum, Escherichia coli, Pseudomonas luteola, and Rhizopus arrhizus (Vijayraghavan, ). The overall economics of the biosorption is influenced mainly by the cost of procuring/growing the biomass. Application of fungal biomass to remove textile dyes from industrial waste water is attractive for. a simple phosphate removal technique, which separates the phos-phate from aqueous system through precipitation [5–8]. However, the chemical precipitation methods require strict control of oper-ating conditions and may potentially introduce new contaminants into the water such as chloride and sulfate ions [2,5,9].
