a
Summary of two or more separate experiments. Survival of worms on the last hour (hour 6) of the assays was estimated with the Kaplan–Meier survival analysis.
b
Juglone: treatment with E. coli OP50 in the first 2 days and then under juglone exposure when C. elegans at L4 stage. LAB: treatment with LAB in the first 2 days and then under juglone exposure when C. elegans at L4 stage. Hour 0 marked the point at which the nematodes were first exposed to juglone.
c
DT50, the time at which half of the worms were dead.
