Identification of genes responsible for absorbing palladium ion in Escherichia coli

Abstract

The capability of Escherichia coli BW25113 to adsorb Pd ions in a single-gene-knockout library was investigated using high-throughput screening. The results revealed that compared to BW25113, nine strains promoted Pd ion adsorption, whereas 22 strains repressed. Although further studies are required because of the first screening results, our results will provide a new perspective for improving the biosorption.
