Spatial distribution of Bacillus surfactins accelerates the spread of PCL1606. a–d MALDI-TOF MSI time-lapse experiments (24 h, 48 h, 72 h) showed the spatial distribution of C14 and C15-surfactin isoforms (m/z 1058 and 1076 M + Na+) when growing a 3610 and b Δmatrix as single colonies or during the interactions between c PCL1606 (right colonies) and 3610 (left colonies) or d PCL1606 (right colonies) and Δmatrix (left colonies). e Comparison between the percentage of Δmatrix and ΔmatrixΔsurf populations in the Bacillus area (BA) after 72 h of interaction with PCL1606. *P value < 0.05 (t student). f Expansion rates of PCL1606 in the absence (blue line) or the presence (green line) of surfactin (1 mg/ml) spotted in a sterile disk (n = 3).
