Enhanced arsenic accumulation in engineered bacterial cells expressing ArsR

Article Abstract:

The overproduction of the metalloregulatory protein ArsR in Escherichia coli resulted in elevated levels of arsenite bioaccumulation but also severe reduction in cell growth. These results open up the possibility of using cells overexpressing ArsR as an inexpensive, high-affinity ligand for arsenic removal from contaminated drinking and ground water.

Density-dependent sorting of physiologically different cells of Vibrio parahaemolyticus

Article Abstract:

Research has been conducted on marine bacterium Vibrio parahaemolyticus. The authors have separated subpopulations from the bacteium's cultures via the use of density-dependent cell-sorting with Percol in order to understand different processes in the cultured cells, and have described the results.

Enhanced mercury biosorption by bacterial cells with surface-displayed MerR

Article Abstract:

Research has been conducted on metalloregulatory protein MerR exhibiting selectivity toward mercury. The authors describe a method developed for mercury removal via generating microbial biosorbents with surface-exposed MerR.
