Changes in cell turgor pressure have been followed in cells of Microcystis sp. transferred to culture medium containing added NaCl at osmolalities of 30–1,500 mosmol kg-1 (≡ 74–3,680 kPa). Upon upshock turgor decreased, due to osmotically-induced water loss from the cell. However, partial recovery of turgor was then observed in illuminated cells, with maximum turgor regain in media containing 30–500 mosmol kg-1 NaCl. The lightdependent recovery of turgor pressure was completed within 60 min… 
Changes in cell turgor pressure related to uptake of solutes by Microcystis sp. strain 8401.
For cells in natural habitats, studies of the permeability of cells to solutes is relevant to the problem of retaining substances that are accumulated by active uptake from solutions of low concentrations in natural waters.

Analysis of cyanobacterial salt acclimation will be directed toward defining the functions of the many unknown proteins upregulated in salt-stressed cells, identifying specific salt-sensing mechanisms, using salt-resistant strains of Cyanobacteria for the production of bioenergy, and applying cyanob bacterial stress genes to improve the salt tolerance of sensitive organisms.

The mutational inactivation of salinity‐inducible proline uptake was found associated with increased sensitivity of the cyanobacterial photosynthetic O2 evolution and nitrogenase activity under salinity and osmotic stresses.
Salt Shock Responses of Microcystis Revealed through Physiological, Transcript, and Metabolomic Analyses
Evidence is provided that M. aeruginosa is relatively salt tolerant in the mesohaline zone and microcystin (MC) release only occurs when the capacity of the cells to deal with salt increase is exceeded.
Physiological and Metabolic Responses of Freshwater and Brackish-Water Strains of Microcystis aeruginosa Acclimated to a Salinity Gradient: Insight into Salt Tolerance
Comparing the physiological responses of two strains of M. aeruginosa, which were isolated from contrasted environments, to increasing salinities illustrated a strain-specific response to salt tolerance, involving compatible solute production.
Permeability and Transport
The workings of individual transport components, such as permease proteins, antiporters, symporters, or ion translocating ATPases, can often best be studied by isolating the catalysts from cell membranes and incorporating them into liposomes or proteoliposomes.

Gas vesicles can be used to measure the hydrostatic pressure (turgor pressure) in prokaryotic cells. Halophilic cyanobacteria have turgor pressures that are substantially less than those of


The Role of Potassium in the Control of Turgor Pressure in a Gas-Vacuolate Blue-Green Alga
The contribution of K+ accumulation to cell turgor pressure was investigated in the gas-vacuolate blue-green alga Anabaena flos-aquae. The cell turgor pressure, measured by the gas vesicle method,
The Interrelations of Cell Turgor Pressure, Gas-vacuolation, and Buoyancy in a Blue-green Alga
Experiments using 14C02 indicate that the increased rate of photosynthesis during the high light exposure is easily sufficient to account for the observed turgor rise, and can bring about collapse of sufficient of the alga's gas vacuoles to destroy its buoyancy.

The assumption that all algal cells behave as “ideal osmometers,” with outer membranes that are permeable to water but not to solutes, during the course of such experiments is incorrect and data need to be adjusted to take account of hyperosmotically induced external solute penetration and/or loss of intracellular osmotica before meaningful estimates of cell turgor and osmotic volume can be obtained.
Ionic relations and the regulation of turgor pressure in the marine alga,Valonia macrophysa
The steady-state turgor pressure in Valonia macrophysa, the giant celled marine alga, changes only 2.5 atm in response to a 25 atm change in seawater osmotic pressure, and potassium transport, which has been shown previously to be sensitive to the turgar pressure, accounts for most of theTurgor regulation at all salinities.
Turgor regulation inValonia macrophysa following acute osmotic shock
A novel mechanism of turgor regulation is exhibited by Valonia macrophysa given hyposmotic shocks greater than about −4 bar, whereupon the protoplasm ruptures and the cell wall stretches irreversibly at a localized site.
The Osmotic Responses of Penicillium ochro-chloron: Changes in Internal Solute Levels in Response to Copper and Salt Stress
It is concluded that the high concentrations of glycerol induced by high external Na+ or Cu2+ had a significant osmotic effect, allowing growth in media of high osmolality.
Osmotic regulation in the marine alga,Codium decorticatum
Codium regulates its turgor as rapidly in the dark as in the light, which suggests that the Cl− pump is not dependent directly on photosynthesis for its energy supply.
Responses of Cyanobacteria to Low Level Osmotic Stress: Implications for the Use of Buffers
The results indicate that metabolic disruption is transient and that, in the long term, growth and metabolic activity remain unaffected.
