FIG. 5.

Effects of changes in resuspension medium on microbial physicochemical cell surface properties. H, hydrophobicity; V, viability; S, Sepharose column assays; A, attachment to solid substrata; EM, electrophoretic mobility. The percentages of experiments where the values of the parameters after treatment were reduced (cross-hatched bars), unchanged (solid bars), and increased (open bars) are shown. For information on reference data and modifications of the parameters see Tables 1 through 8. c-lim, carbon limited; n-lim, nitrogen limited.
