Diversity and Performance of Sulphate-Reducing Bacteria in Acid Mine Drainage Remediation Systems

Microbial diversity in acid mine drainage from eMalahleni, Mpumalanga, South Africa. Enrichment of SRB improves its performance in sulphate reduction. Microbial community shows synergy between SRB Proteobacteria and facultative Bacilli. Sulphate reduction of 85% and cadmium reduction of 98% were observed within 7 days of continuous operational mode. The microbial community showed wider substrates utilisation.
