Abstract:
NaCl.Glycerol and trehalose were the most prominent compatible solutes in C.krusei.The glycerol production was enhanced with the osmotica concentration increasing and NaCl,KCl were much effective than manntiol.The glycerol concentration was increased 74%,63%,57% and the intracellular glycerol was 3.1,2.4,1.8 fold to the control respectively when 0.6mol/L NaCl,KCl and mannitol existed.During the early stage of fermentation,the trehalose all decreased compared with the control.However,the trehalose content was higher than the control in the late stage of fermentation when 0.6mol/L KCl and mannitol existed.The trehalose content was 1.6 and 1.4 fold to that of control respectively.
