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.
