  1. aOnly those consortia that avoided extinction were analyzed. bBold font: statistically significant differences between the test and ancestral mutualistic consortia (P < 0.01). cDefinitions: Panc, ancestral strain of BW25113 (∆proC); Tanc, ancestral strain of BW25113 (∆trpC); Pevol, evolved strain of BW25113 (∆proC); Tevol,a, evolved strain of BW25113 (∆trpC); Tevol,b, evolved strain of BW25113 (∆trpC). dTevol,a and Tevol,b are two genetically different strains of BW25113 (∆trpC) that emerged within the B2 mutualistic consortium
