Genome-guided bioprospecting for novel antibiotic lead compounds.
Antimicrobial resistance continues to pose a threat to health and wellbeing. Unmitigated, it is predicted to be the leading cause of death by 2050. Hence, the sustained development of novel antibiotics is crucial. As over 60% of licensed antibiotics are based on scaffolds derived from less than 1% …

Bioprospecting of plants species with potential to uptake inorganic chemical species from gold mine tailings and acid mine drainage
In South Africa, mining of gold and coal has huge negative impacts on the environment. This is due to the exposure of sulphide-bearing minerals such as pyrite (FeS2) to oxygenated water during and after the extraction of ore deposits which results in the formation of acid mine drainage (AMD). Acid …
