Role of K+ and amino acids in osmoregulation by the free-living microaerophilic protozoon Hexamita inflata
Biagini, G; Kirk, Kiaran; Schofield, P.R.; Edwards, Michael
Description
The primitive free-living protozoon Hexamita inflata was found to maintain a cell volume of approximately 260 fl under standard culture conditions. On increasing the extracellular osmolality the volume decreased and the cells remained shrunken for > 30 min. By contrast, a decrease in the external osmolality resulted in a transient increase in cell volume which was followed by an efficient 'regulatory volume decrease' (RVD). H. inflata contains high concentrations of amino acids, with alanine...[Show more]
