The halophilic fungus Hortaea werneckii and the halotolerant fungus aureobasidium pullulans maintain low intracellular cation concentrations in hypersaline environments

A study is conducted to investigate whether in halophilic Hortaea werneckii and in halotolerant Aureobasidium pullulans osmotic adjustments of sodium and potassium also occur in response to osmotic stress. Small fluctuations of cation concentrations are observed after a hypersonic shock in nonadapted Aureobasidium pullulans similar to those in salt-adapted Hortaea werneckii, which additionally confirmed better regulation of ionic homeostasis in the latter.
