Three lichen-associated bacterial isolates were subjected to headspace SPME GC/MS analysis to identify isolate-specific VOC profiles. An overlay of the respective TIC chromatograms illustrates the presence of specific metabolites in the headspace of Bacillus pumilus43P2BR (empty squares), Pseudomonas umsongensis 313P5BS (filled squares), and Stenotrophomonas rhizophila 418P4B (filled triangles). Identified Bacillus-specific compounds were: 1-butanol (5□) and 3-methyl-2-pentanone (8□). Methyl thiocyanate (7■) was identified as Pseudomonas-specific compound. Stenotrophomonas-specific compounds were: 2-butanol (3▴) and 2-methyl-1-propanol (4▴). More details in Table S2.
