Table 1. Maximum yield of P. fluorescens Pf0-1 wild-type and mutant Δ3463 strains in nutrient-poor liquid medium.

Treatment	Maximum yield * (CFU per ml)
Pf0-1 wild-type+10% cell-free Pedobacter supernatant	7.99±0.013
Pf0-1 wild-type+10% boiled cell-free Pedobacter supernatant	7.96±0.022
Δ3463+10% cell-free Pedobacter supernatant	8.00±0.021
Δ3463+10% boiled cell-free Pedobacter supernatant	7.99±0.016

*The maximum yield calculated at time point  = 7.5 h is the mean of tree replicates per treatment. The variation between the replicates is indicated as ± s.d.

One-way ANOVA did not reveal difference between the treatments p>0.05.
