Bacterium-bacterium inhibitory interactions at the phylogenetic level^a

^aEighty-six marine bacterial isolates belonging to the α-proteobacterial (Alpha) (n = 19), Bacteroidetes (Bactero.) (n = 19), Alteromonadales (Altero.) (n = 28), and Vibrionales (Vibrio.) (n = 20) groups were examined for production and sensitivity to inhibitory molecules against one another. Isolates were operationally defined as either free-living (F) or particle-attached (P) based on the isolation procedure (see Materials and Methods).
