1)Boil Method

1.Monitor OD of yeast and incubate until it becomes OD≒1.
2.Centrifuge yeast at 3500 rpm for 5 min
3.Discard the supernatant
4.Pipette the culture residual substance and transfer 1 ml of it to an Eppendorf tube
5.Centrifuge on FLASH and then decantate it
6.Add 1 ml of distilled water
7.Vortex
8.Centrifuge yeast at FLASH
9.Discard the supernatant (wash 1st time)
10.Repeat steps 6-9 (wash 2nd)
11.Repeat steps 6-9 (wash 3rd)
12.Cryopreservation
13.Add 1 ml of distilled water and vortex
14.Boil it with hot water for 10 min
· Fit the tube in the sponge and put it in boiling water
(· Keep the fire between low to medium heat)
15.Centrifuge at 10000 rpm for 5 min, and remove 900μl of the supernatant
16.Measure Na+ concentration(Atomic Absorption Spectrometry)
