||P.286 left column bottom paragraph: "In this study, E. coli was selected as a target of the structome analysis because a large number of molecular biological studies were performed with this microorganism. E. coli cells were cut into 65 nm thick serial ultrathin sections after rapid cryofixation and freeze-substitution. In addition to the structome analysis by serial ultrathin sectioning, PCM (phase contrast microscopy) and SEM (scanning electron microscopy) examinations were performed on the same bacterial sample because the fundamental morphological studies were achieved with these observation techniques."
||P.288 left column, bottom paragraph: "The volume of each of the nine E. coli cells was calculated using measurements taken with ImageJ/Fiji software, as described in the Materials and Methods section. Data regarding the three-dimensional profiles of each cell are shown in Table 4 and the proportion (%) of OM, periplasm, PM and cytoplasm are summarized in Fig. 3. The average whole-cell (as outlined by the OM) and cytoplasmic (as outlined by the PM) volumes were 1.16 ± 0.20 fl (ranging from 0.94 to 1.54 fl) and 0.92 ± 0.16 fl (ranging from 0.75 to 1.19 fl), respectively. In addition, the average OM, PM, and periplasmic volumes were 0.02 ± 0.00 fl (ranging from 0.01 to 0.02 fl), 0.02 ± 0.00 fl (ranging from 0.02 to 0.03 fl) and 0.23 ± 0.07 fl (ranging from 0.17 to 0.35 fl), respectively." femto-liter (fl)=μm^3=10^-15L
