Yeasts in marine and estuarine environments

December 2012

Yeasts and other fungi are prevalent in marine and estuarine ecosystems where they play an important role in the food web. Marine yeasts are unique in performing fermentations under high salt concentrations. The mechanism underlying the high salt tolerance involves the ability to accumulate high concentrations of sodium without becoming intoxicated, and the exclusion of excessive sodium from the cytoplasm. Overall, the...
