FIG. 8.

Cell images observed by electron microscopy. Cells were fixed in the cultures, directly placed on copper grids, negatively stained, and observed. (A) Cells were grown to an OD₆₀₀ of 0.05 in the standard medium. (B and C) Cells grown in the standard medium were transferred to a medium without supplementation for lipid synthesis and incubated for 1 and 2 h, respectively. (D) Cells grown in the standard medium were incubated with chloramphenicol at 37°C for 1.5 h. Bar, 0.5 μm.
