Yeast experiments: Lysozyme

  • Today we began the tests with the yeasts transformed with the following constructions: YEP+pDLD-Lysozyme and YEP+Adh1-Lysozyme.

  • The pre inocula made yesterday grew. We inoculated it in 50mL of YNB Glucose Ura- or YNB Ethanol Ura-. The wild type yeast is Ura- so we grew it on YNB Glucose Ura+. The inocula grew for 4 hours in 30ºC and 150rpm until the OD 1,3 before the induction with lactic acid.
  • We performed the induction 5 hours long. We mesured the OD every one hour to construct a growth curve. At the end of the 5 hours we pelleted the culture, colected the supernatant and freezed the pellet to analyze in SDS-PAGE tomorrow.
  • We also dripped drops of the supernatant in filter paper discs and placed them in a Lactococcus lactis plate. We hope to see inhibition zones surrounding some of the filters.
  • The Yeasts inoculated in YNB Ethanol media didn't grow enough to begin the induction until the end of the day.
