Bacterial bioremediation of metal-contaminated soils in Sub-Saharan Africa: systematic review
A systematic review identifies Bacillus and Pseudomonas as the predominant genera in bacterial bioremediation of mining-contaminated soils across Sub-Saharan Africa.

What the study showed
Twenty-six types of metal waste from mining were documented, with heavy metals accounting for 87.4% of cases. Bacillus and Pseudomonas showed functional redundancy and multiple bioremediation mechanisms. Bacteria associated with Pb and Cd displayed high co-occurrence similarity (Jaccard index 0.78).
How it was done
Systematic review synthesizing articles published from 2005 to February 2026, covering metal-resistant bacteria, tolerance mechanisms, and bioremediation efficiency in Sub-Saharan African soils.
Risk of bias
The abstract itself acknowledges restricted geographical scope of included studies and limited field-based application, constraining generalizability. Reported efficiency data derive predominantly from laboratory conditions.
What this study does NOT prove
The study does not demonstrate bacterial bioremediation efficacy under real field conditions in Sub-Saharan Africa.
In clinical practice
Findings carry no direct clinical application; relevance is confined to environmental management of contaminated soils. Field data are insufficient to support large-scale remediation recommendations.
Limitations
The abstract itself acknowledges restricted geographical scope of included studies and limited field-based application, constraining generalizability. Reported efficiency data derive predominantly from laboratory conditions.
