P. piscicida  JCM 20779 cultured in Difco Marine Media 2216 in the absence (a) and presence (b) of cotton scaffold. (c): Overlaid UPLC‐PDA chromatograms showing absorbance at 390 nm for the methanol extract of the planktonic cell pellet of P. piscicida JCM 20779 grown without cotton and the methanol extract of biomass associated with the cotton scaffold for P. piscicida JCM 20779 grown with cotton. Known alterochromide variants are indicated. A = alterochromide A, B = alterochromide B, BrA = bromoalterochromide A, BrB = bromoalterochromide B etc
