Fig. 3From: Adaption to glucose limitation is modulated by the pleotropic regulator CcpA, independent of selection pressure strengthPhenotypic characterization of evolved strains in batch culture The evolved strains were revived in batch culture and the growth characteristics determined (a). b Evolved strains sediment during growth. Overnight cultures of Genr0 and 445C1 in CDMPC are shown. c Sedimentation is caused by the formation of long cell chains. Typical pictures are shown for Gen0 and 445C1 grown for 16 h in CDMPC. The cells were visualized using a Zeiss light microscope and a Zeiss digital camera. Magnification, × 1000Back to article page
