  1. S. coelicolor LW34 and LW33 were grown in duplo in liquid SMM (growth curves (GC) 1 and 2). Samples were taken at different phases of growth (e arly, m id and l ate t ransition (eT, mT, lT), and s tationary (S) phase). The sampling time is given in hours of growth in brackets underneath the determined OD450. Production of actinorhodin (Act) and (undecyl-) prodiginines (Red) is given in μg /dry cell weight mg-1.
