Abstract The present work reports the bioremediation ability of cow dung isolated bacterial strain Cellulosomicrobium cellulans KHP3 identified by applying PCR amplification and rRNA gene sequencing. The potential of C. cellulans KHP3 to tolerate different concentrations of heavy metals was investigated by growing the novel strain on nutrient agar medium supplemented with increasing concentrations (in ppm) of heavy metals i.e., Chromium (50–1500) Copper (50–200), and Zinc (50–200).
