Germicidin A. (A) LC-MS analysis culture broth extract of S. coelicolor's spores after 6 h germination in R3 medium with glycerol. MS chromatogram recorded for m/z 197.118. (B) Mass spectrum of compound with tR = 6.48 min. Acquired m/z 197.1188 corresponds to [M + H]+ of germicidin A with the theoretical m/z 197.1178. (C) LC-MS analysis of germicidin A authentic standard. MS chromatogram recorded for m/z 197.118. (D) Mass spectrum of germicidin A. Acquired m/z = 197.1170 corresponds to [M+H]+ of germicidin A with the theoretical m/z = 197.1170.
