Chatting Coordinates Heterogeneity in Bacteria
Published:04 Aug.2017    Source:Science Daily


Bacterial populations can, under certain conditions, react in a coordinated manner to chemical messages produced by a minority of their members, as a new theoretical study carried out by biophysicists led by Professor Erwin Frey.

Bacterial cells communicate with one another by using chemical signal molecules, which they synthesize and secrete into their surroundings. By this means, the behavior of an entire population can be controlled and coordinated. Professor Erwin Frey is the Chair of Biological and Statistical Physics at LMU, and has now shown theoretically how this can be accomplished even when only a subset of cells actually emits the requisite signals.
