The Yeastguard: Results

We confirm the following Biobricks:

Mechanism of recognition

Parts:

  • BBa_K284002 - JEN1 Promoter from Kluyveromyces lactis -
  • BBa_K284003 - Partial DLD Promoter from Kluyveromyces lactis


Devices to JEN1 and DLD promoters characterization:

  • BBa_K284020 - EYFP regulated by lactate responsive promoter (JEN1)
  • BBa_K284021 - EYFP regulated by lactate responsive promoter (DLD)
  • BBa_K284023 - EYFP regulated by constitutive promoter Adh1


Killing mechanism

Parts:

  • BBa_K284001 - Lysozyme from Gallus gallus


Devices to Lysozyme characterization:

  • BBa_K284016 - Lysozyme constitutive expression
  • BBa_K284017 - Lysozyme expression in response to lactate (DLD promoter)
  • BBa_K284015 - Lysozyme expression in response to lactate (JEN1 promoter)




Yeast experiments: Lysozyme

Growth curve



Lactococcus lactis



SDS-PAGE

We made two SDS-PAGE gels, one for the supernatant and the other for the total yeast extract. We couldn't load the pellet ethanol samples maybe because of residual ethanol at the pellets; the alcohol hinder the entry of the sample in the well.

Unfortunately we couldn't see any protein band in the gel neither in the supernatant one nor in the total extract one. Maybe we loaded insufficient amounts of sample.
