    "abstract": "We present a simple model based on a reaction-diffusion equation to explain\npattern formation in a multicellular bacterium (Streptomyces). We assume\ncompetition for resources as the basic mechanism that leads to pattern\nformation; in particular we are able to reproduce the spatial pattern formed by\nbacterial aerial mycelium in case of growth in minimal (low resources) and\nmaximal (large resources) culture media.",
