GC–MS total ion chromatograms of S. plymuthica WS3236 (top) and E. coli pET28b-ptetO::sod_gfpv2 (bottom) VOCs produced in TB medium within the first 24 h hours of cultivation. Mesitylene (M) was added as an internal standard with a concentration of 250 µg/mL. The amount of sodorifen (S) produced heterologously by E. coli is significantly higher combined with better purity compared to S. plymuthica
