UC San Diego Synthetic Biologists Redesign the Way Bacteria 'Talk' to Each Other (VIDEO)
Caption
Bioengineers at the University of California San Diego have redesigned how harmless E. coli bacteria 'talk' to each other. In this video, In particular, the researchers used low and medium concentrations of p-coumaric acid to cause populations of bacteria with both the new inducible quorum sensing circuit and the lysis gene to switch between no delivery and steady oscillations of cargo delivery. The researchers also demonstrated that subjecting bacteria to high concentrations of p-coumaric acid wiped out all the cells by forcing them to constantly produce the lysis proteins, independent of population size.
