The dissolutions of cells of marine and terrestrial bacteria in distilled water were manifested by the turbidity decrease, the release of cell materials, the restoration of turbidity, and the decline of viability. The three test bacteria showed a rapid decrease of turbidity immediately after suspending. The rapid decrease in turbidity did not mean the degree of bacteriolysis. The restoration rates of turbidity by adjusting the mineral concentration in the suspending medium to ASW level were correlated with the viability of cells in the suspensions indicating the degree of damage of cells. The dissolution of 1055-1 in distilled water may be due to a damage of an individual cell inflicted by the deficiency of the divalent cations in the medium, while in case of V. parahaemolyticus it may rather be due to the plasmoptysis of cells in the hypotonicity. The dissolution of cells in distilled water could not be observed in P. fluorescens.
