Figure 1. B. subtilis fed worms live longer and die because of different reasons than E. coli fed worms. (A) Life span curves for adult worms maintained on E. coli (OP50) or on different wild type strains of B. subtilis: PY79, 3610, and 168. (B) Age-related mortality for worms fed B. subtilis or E. coli (see also Figure S2 for life span and death frequency over time data). (C) Life span curves for adult worms maintained on E. coli, B. subtilis, or the sporeless B. subtilis mutant (1S143). (D) Life span curves for adult worms maintained on live E. coli, UV-killed E. coli, live B. subtilis, or UV-killed B. subtilis. (E) Life span curves for adult worms maintained on E. coli; on B. subtilis; or on E. coli as late L4 stage and then switched to B. subtilis. (A-E) y-axis indicates percentage of worms that are alive. x-axis indicates day of adulthood. See also Table S1.
