Abstract

This article focuses on identifying genes in Escherichia coli BW25113 responsible for the biosorption (bio-adsorption) of palladium (Pd) ions using a high-throughput screening of a single-gene-knockout library known as the Keio collection. The study found nine gene knockouts that enhanced Pd adsorption and 22 that repressed it, suggesting these genes influence Pd ion uptake. Overexpression of certain repressive genes, particularly yebZ which encodes a metal-transporting transmembrane protein, improved Pd adsorption capacity. These findings provide a genetic basis for enhancing microbial biosorption of palladium, a precious metal important in industry, and offer insights for developing environmentally friendly metal recovery methods. Further research is needed to clarify the roles of these genes in Pd biosorption mechanisms.
