Morphology of S. lividans 66 and its derivatives PM01 and PM02 in submerged culture. PM01 was obtained after 70 generations in a nitrogen-limited chemostat at a dilution rate of 0.1 h-1. PM02 was obtained after evolving PM01 for another 30 generations in a phosphate-limited chemostat at 36°C and a dilution rate of 0.1 h-1. Top row: growth of strains in a baffled shake flask for 30 h on TSBS. Bottom row: cultivation of strains in a 900 ml bioreactor in TSBS media after 24 h of growth. Scale bar, 200 μm.
