From: Widespread pyocyanin over-production among isolates of a cystic fibrosis epidemic strain
Pyocyanin production by sequential isolates from CF patients D-F. Production of pyocyanin in culture supernatants during growth of LES isolates in L-broth is shown for isolates from three CF patients (patient D-F). Chronological order of isolation is indicated by colour from the earliest to the most recent in the following order : yellow (1995), red (1996), blue (1998), black (2000) and pink (2002). Different isolates from the same year are indicated by different shapes.
