The present investigation was carried out to study the removal of heavy metal by Pseudomonas sp. Isolated from garden soil samples by employing plating techniques. The isolated bacterial members were identified by Gram’s staining, motility, IMViC and sugar fermentation methods. The isolated bacterial members were used as inoculants for heavy metal removal treatments. Biosorption of three heavy metals namely Zinc, copper and Nickel were conducted using individual cultures of Pseudomonas sp. The Zinc biosorption studies using individual cultures of Pseudomonas sp. resulted 99.3% of sorption at pH 5, temperature 32oC and biomass concentration of 0.5 mg/ml in 50 minutes period of contact time.
