Abstract:
Background: Informal handling and disposal of electronic waste can release heavy metals into soil and select for metal-tolerant microorganisms. This study aimed to isolate and identify heavy metal-tolerant bacteria from soils around two informal e-waste handling sites in Ilorin, Nigeria, assess changes in dissolved metal concentrations during 21 days of sequential enrichment with waste printed circuit boards (WPCBs), and evaluate the isolates as potential candidates for future bioleaching studies.
