Ethanol Yeast Experiment 2022

Introduction

We will add a sample of ethanol solution to a yeast culture and measure the growth afterward. This experiment is to determine what amounts of ethanol solution are best for the tress experiment on our class knockout genes.

Materials

  • Corning COSTAR 96-well clear flat-bottom assay plate
  • Wild-type yeast in 2x synthetic complete media at an OD600 of 0.1-0.2
  • Ethanol concertation of 1M (labeled ETH01M)

Procedure

  1. Item 1 Make the ethanol solution by add 942µl of water and 58µl of 100% ethanol
  2. Item 2 Collect well a clear flat-bottom assay plate
  3. Item 3 Vortex yeast culture for about 5 seconds
  4. Item 4 Put 50µl of the yeast culture into all 12 wells.
  5. Item 5 In the 1st well add 1µl of your ethanol solution and 49µl of H2O
  6. Item 6 In the 2nd well add 2µl of your ethanol solution and 48µl of H2O
  7. Item 7 In the 3rd well add 3µl of your ethanol solution and 47µl of H2O
  8. Item 8 In the 4th well add 4µl of your ethanol solution and 46µl of H2O
  9. Item 9 In the 5th well add 5µl of your ethanol solution and 45µl of H2O
  10. Item 10 In the 6th well add 8µl of your ethanol solution and 42µl of H2O
  11. Item 11 In the 7th well add 10µl of your ethanol solution and 40µl of H2O
  12. Item 12 In the 8th well add 20µl of your ethanol solution and 30µl of H2O
  13. Item 13 In the 9th well add 27µl of your ethanol solution and 23µl of H2O
  14. Item 14 In the 10th well add 35µl of your ethanol solution and 15µl of H2O
  15. Item 15 In the 11th well add 41µl of your ethanol solution and 9µl of H2O
  16. Item 16 In the 12th well add 50µl of your ethanol solution and 0µl of H2O
  17. Item 17 In E column 12th well add 0µl of your ethanol solution and 50µl of H2O
  18. Item 18 Put your well clear flat-bottom assay plate into the incubator and let sit.
  19. Item 19 Wait and observe the growth or death


Knockout Yeast Ethanol Stress Experiment

Introduction

Our class had some success with knocking out certain yeast genes. We take these genes, add the ethanol solution to a culture of said knockout genes and see how the yeast without those genes live or not.

Materials

Corning COSTAR 96-well clear flat-bottom assay plate

Wild-type yeast in 2x synthetic complete media at an OD600 of 0.1-0.2

Ethanol concertation of 1M (labeled ETH01M)

YCR095C yeast knockout strand

YER076C yeast knockout strand

YER186C yeast knockout strand

YHR033W yeast knockout strand

YJL133C-A yeast knockout strand


Procedure

Make/find your ethanol solution, add 942µl of water and 58µl of neat ethanol

Collect well a clear flat-bottom assay plate

Vortex yeast culture for about 5 seconds before adding to the wells

Add 50 µl of wild yeast culture into well 1.

Add 50 µl of knockout strain yeast culture #1 into well 2

Add 50 µl of knockout strain yeast culture #2 into well 3

Add 50 µl of knockout strain yeast culture #3 into well 4

Add 50 µl of knockout strain yeast culture #4 into well 5

Add 50 µl of knockout strain yeast culture #5 into well 6

Then 50 µl of the ethanol solution to the same 6 wells

Put your well clear flat-bottom assay plate into the incubator and let sit

Wait and observe the growth
