Fig. 1From: Complete genome sequence of the phenanthrene-degrading soil bacterium Delftia acidovorans Cs1-4Top panel: Transmission electron micrograph of negatively-stained culture fluids from phenanthrene-grown D. acidovorans Cs1-4. Nanopods and related structures are indicated by the black arrows, flagella are shown by white arrows. Features indicated by numbers are: 1.) linear structures, 2.) globular elements, 3.) blocky formations and 4.) linear structure with globular element at terminus. The scale bar at bottom right represents 500Â nm. Bottom panel: Thin section transmission electron micrograph of D. acidovorans Cs1-4 cell grown as a biofilm on phenanthrene. A nanopod growing from the cell surface is enclosed by the box and arrows indicate segments of other nanopods in the biofilm matrix. The scale bar at bottom right represents 200Â nmBack to article page
