Abstract
This aim of this research was to determine the tolerance ability of Bacillus lentus, Bacillus firmus, and Pseudomonas aeruginosa. The soil sample was analysed for it heavy metal content lead was found to be in abundance beyond tolerable limit followed by cupper. Several bacterial specie were also isolated and identified from the sample and some selected species were tested for their tolerance ability in different heavy metal concentration, It was recorded that pseudomonas aeruginosa was tolerant to lead (Pb) at 800 mgl-1 Bacillus lentus to cupper at 860 mgl -1 and Bacillus firmus to chromium at 1000mgl-1. It was concluded that despite the toxicity of some heavy metals some bacterial specie were still able to withstand the environment.
