Using NaHS and S₈ to treat S. coelicolor M145.

Different concentrations of NaHS or S₈ (20, 50 and 100 µM) were added to agar plates before inoculation of S. coelicolor M145 spores. Control was the plate without addition of the chemicals. After inoculation, the plates were incubated at 30 °C for 6 days and then subjected to analysis.

A. Total ACT production of S. coelicolor M145. Data were from three repeats.

B. S₈ increased ACT production of S. coelicolor M145. Images were captured from the reverse side of the plates.

C. S₈ affected spore formation of S. coelicolor M145. Images were captured from the front side of the plates.
