Fig. 1

Co-cultures of S. iranensis and C. reinhardtii (a, b). Co-cultivation in light and dark with and without S. iranensis in TAP medium (a) and on agar (b). Loss of green coloration indicates killing of C. reinhardtii. c MALDI-IMS analysis. Top: schematic position of the S. iranensis colony, sterile TAP agar and TAP agar containing C. reinhardtii on the ITO-slide. MALDI-IMS images indicate color-coded abundance of ion m/z = 1069.12 ± 0.6 Da (azalomycin F3a, [M + H]+) and ion m/z = 1083.16 ± 0.6 Da (azalomycin F4a, [M + H]+). Color code: blue = low abundance, red = high abundance of ion. MALDI-IMS shows that both azalomycins are released only in co-cultivation of S. iranensis with C. reinhardtii which was inoculated into the left half of the agar.
