DOI: 10.1371/journal.pcbi.1009877
Abstract: Most microbes live in spatially structured communities (e.g., biofilms) in which they interact with their neighbors through the local exchange of diffusible molecules. To understand the functioning of these communities, it is essential to uncover… read more here.
