From: Identification of genes essential for pellicle formation in Acinetobacter baumannii
Pellicle formation by A. baumannii 17978hm parent, cpdA::Tn(0249) and cpdA::Tn(1266) strains. A. baumannii strains were grown in Luria-Bertani broth and analysed after a 72 h incubation at 25 °C in the absence of light. Pellicle material was assessed visually. (a) 17978hm parent strain; (b) cpdA::Tn(0249) complemented mutant strain showing developed pellicles at the interface between the liquid and air; and (c) cpdA::Tn(1266) mutant strain negative for pellicle formation. Arrows identify the pellicle material
