"Measurements of volume of cytoplasmic water in titrations of
non-growing cells with the plasmolyzing agent NaCl were used to obtain volumes of
“bound” water (presumably water of macromolecular hydration) and cytoplasmic osmotic
coefficients for cells grown in medium of low (0.10 OSM) and moderate (0.28 OSM) osmolarity. The volume of bound water is similar in the two osmotic conditions (volume of bound water=0.40(±O.04)µl/mg dry wt), and corresponds to approximately 0.5g H2O/g cytoplasmic
macromolecule." |
