| Abstract: | Through the experiments on dealing with yeast under such stress as cold shock and heavy metal ions, we come to the conclusion that the best single stress in the accumulation of trehalose is as follows： dealing with yeast in the solution of 1.2 mol/L NaCl for 30 minutes; dealing with yeast in the solution of 0.9 mol/L KCl for 60 minutes; dealing with yeast in the solution of 0.6 mol/L MgSO4 for 90 minutes; dealing with yeast in the solution of 1.2 mol/L CaCl2 for 90 minutes; dealing with yeast in the solution of 0.8 mol/L A1Cl3 for 6 hours; dealing with yeast in the solution of 0.4 mol/L FeCl3 for 3 hours; dealing with yeast at the temperature of 0℃ for 15 seconds. |
