||P.180 right column 2nd paragraph: "From the data reported in the literature the average values for cell length and width were adapted as 2.6 and 0.65µm, respectively (primary sources 66-69). Cell surface area (S), cell volume (V), and dry weight (Wt) were calculated as 6.0×10^-8 cm^2, 9.0×10^-13cm^3, and 2.2×10^-13g, respectively. The cell dry weight was calculated based on a water content of 78% (primary sources 70 & 71) and a specific gravity (primary source 72) of 1.135."
