Atomic force microscopy of bacterial surface membranes


The morphology of several marine bacterial isolates (Alteromonas sp. AltSIO, Pseudoalteromonas TW7, Vibrio SWAT-3, Flavobacterium BBFL7) (Figs. A,B,&C) and marine bacterial natural assemblages were extensively studied with AFM at different growth stages under differing conditions. Treatments included the addition of antibacterial agents such as silver nanoparticles and antibiotics. AFM data of the bacteria was collected to observe the cell structure and investigate formation of blebs and morphological changes at the nanoscale. AFM probing was also used to investigate the bio-mechanical properties of marine bacteria.


Raw AFM data is stored in Veeco Nanoscope format and available upon request to Dr. Azam
