Abstract
In order to investigate the role of glutathione in response to salt stress in the thermophilic fungus, Thermomyces lanuginosus, the biomass and the intracellular pool of protein and the glutathione + glutathione disulphid (GSH + GSSG) was measured for four days in a medium with NaCl or KCl added and in the basal medium. Due to the osmotic and ionic stress imposed by the salts, the growth of T. lanuginosus was delayed and the inhibitory effect of KCl exceeded that of NaCl. Glutathione seemed to be involved in the response of T. lanuginosus towards high concentrations of salt, as the level of stress was negatively correlated with the amount of total glutathione. Salt stress did not result in an increased intracellular protein production. GSH accumulated while nutrients were abundant and were subsequently degraded later, suggesting that nutrients stored in GSH are used when the medium is depleted.
