An innovative approach to bioremediation of mercury contaminated soils from industrial mining operations
• A bulk natural substrate, zeolite, was bio-functionalised with encapsulated P. veronii.
• This remained viable and functional after long term storage.
• Bio-functionalised zeolite increased GEM flux by 104.
• A concomitant reduction in GOM emissions was also observed.
• Bio-functionalised zeolite shows potential for remediation of mercury-contaminated sites.
