Abstract

The bioremovel of nickel ions by Pseudomonas fluorescens was studied for the period of eight days by exposing to different concentrations of nickel (250, 500, 750 and 1000ppm). Experiments were designed to study the effect of dead cells and sugars on the biosorption of nickel ions. Atomic absorption spectrophotometric (AAS) analysis was carried out for the samples at an interval of two days. The highest nickel uptake was at 1000ppm concentration. Metal binding by bacteria has been shown to be profoundly influenced by the concentration of the metal.
