TEM micrographs of Rhodococcus sp. strain Q15 cells obtained during growth on glucose-acetate or diesel fuel at 5°C. (A) Strain Q15 grown on glucose-acetate and fixed in the presence of ruthenium red. The organism occurred as single cells which were surrounded by EPS consisting of a delicate web of fibers consistent with bacterial capsular material. (B) Floc phase cells of strain Q15 grown on diesel fuel and fixed in the presence of ruthenium red. In thin sections, finely contrasted clusters of EPS material surrounded cells within the flocs. The arrow indicates an intracellular inclusion. Bars = 500 nm.
