In contrast to other lipid classes, the average phospholipid concentration did not
decrease during stationary phase, but it rather increased as also observed under PDB
during the stationary phase and ranged between 2 and 12 mg (Table 10). During the
stationary phase, the concentration o f acetone mobile polar lipids slightly decreased
during the stationary phase when UDA+PDB and UDA are the carbon substrates (Table
10). When PDB was the carbon substrate the content of acetone mobile polar lipids
increased 3 times during stationary phase compared to exponential phase (Table 10).
