Fig. 5. The number of P. multimicronucleatum cells with extra CVCs (filled circles) and the cell density (open circles) as a function of the time after the cells were returned to their 84 mosmol l^-1 axenic culture medium (at 0 time) from a 4 mosmol l^-1 standard saline adaptation solution. The percentages of cells with extra CVCs were determined from 300 cells at each time selected at random. The cell density is the percentage compared to the density at -18 h, the time when the cells were transferred for adaptation into the standard saline solution from the axenic culture medium. Each symbol is the mean of two calculations obtained from two experimental series. Bars indicate ± S.D.
