From: Bacterial social interactions drive the emergence of differential spatial colony structures
Pairwise social interactions in bacteria. a Cell interactions implemented through the production of diffusible chemicals. The chemicals from one species may be deleterious (e.g, toxin), beneficial (e.g., public good), or neutral to the growth of the other. b Six distinct types of social interactions in a two-species population, including commensalism, neutralism (control), amensalism, mutualism, parasitism, and competition
