Figure 5

DMTS, DETS, DATS, DPTS, but not DBTS, show antibiotic activity via the gas phase. A 20 µL drop of an 80 mM solution of the test thiosulfinate was placed in the lid of a Petri-dish and the base with bacteria-seeded agar inverted over it. Thus, the agar did not come into contact with the droplet. Inhibition of growth was visible as a halo with reduced bacterial growth.
