Bacterial Culture Optimization for Enhanced Lead Oxide Nanoparticle Synthesis: Towards Sustainable Nanotechnology

Abstract

The main causes of heavy metal pollution today, are a variation of actions in the metal processing and electroplating industries. A good alternative to removing heavy metals from locations affected by metals is to use inexpensive microorganisms. The present study, with its significant findings, is centered on removing and sorting metal-tolerant bacterial species from the wastewater used in electroplating. Bacterial strains were screened for lead tolerance, depending upon the growth. The isolated bacterial strain was identified as Cupriavidus gilardii and it has shown maximum growth at numerous optimised conditions, i.e. pH (8), temp. (37⁰C), metal dose (200 ppm) and contact time (72 hrs).
