Saltwater Torture

Pilot experiment

Introduction: This experiment is testing how much salt will stress out the yeast without killing them. Our goal of this experiment is to see how much salt is needed to allow the yeast to grow while altering their growth curve without killing them. In this pilot experiment we tested wild yeast strains against different molarities of salt water. Looking at the growth curve data will help us determine which molarity of salt water stressed out the yeast without killing them.

Materials:

  • H2O
  • NaCl (table salt)
  • 12 2 ml centrifuge tubes
  • Yeast cells

Procedure: Calculate the dilution from 4 M saltwater into the varying amounts below.
