Abstract
Biosorption of Chromium by Bacillus subtilis and Pseudomonas aeruginosa Isolated from Waste Dump Site
This study focused on biosorption of Chromium using Pseudomonas aeruginosa and Bacillus subtilis. The study was performed by varying the parameters that determine the efficiency of biosorption, i.e. pH, biomass concentration, metal concentration, temperature and contact time. The results obtained shows that higher percentage of Chromium biosorption was recorded with Bacillus subtilis. The optimum value for each of the parameters was obtained in the following order; for pH, optimum value was 4.0, with highest biosorption percentage of 80.6 and 86.7% for Pseudomonas aeruginosa and Bacillus subtilis respectively. Highest biosorption percentage of 83.0 and 86.7% were recorded at concentration of 2ml for Pseudomonas aeruginosa and Bacillus subtilis respectively for biomass concentration. Chromium concentration produced 73.6 and 86.7% highest biosorption at 5ppm for Pseudomonas aeruginosa and Bacillus subtilis respectively..
