*a*Surface tension in spent DMB medium after 2 days of incubation at 20°C is given as the mean of three replicates ± the standard deviation, except for control 1, which is given as the mean of six strains ± the standard deviation. Surface tension in uninoculated DMB medium was 71 mN m^{−1}.↵

*b*Swarming velocity on PDA and ABTG media after 24 and 48 h of incubation at 20°C is given as the mean of 3 to 22 strains ± the standard deviation, except for those for groups A1 and control 2, which represent one strain.↵

*c*Strain group without CLP production.↵

*d*A1 mutant impaired in the peptide synthetase responsible for amphisin production (Koch et al., submitted).
