Researchers Examined about 35,000 Chemical Reactions to Determine the Social Roles of Bacteria (image) National Science Foundation Share Print E-Mail Caption Scientist from the Massachusetts Institute of Technology, along with researchers from the French Research Institute for Exploitation of the Sea and Woods Hole Oceanographic Institution in Massachusetts, studied whether population-level organization exists for bacteria in the wild. They assembled an all-against-all battleground for 185 closely-related, but distinct, members of an ocean-based family of bacteria called Vibrionaceae and examined about 35,000 chemical reactions to determine whether some bacteria play different social roles.
