The Yeastguard: Results
We can build and confirm the following Biobricks:
Mechanism of recognition
Parts:
- JEN1 Promoter from Kluyveromyces lactis
- Partial DLD Promoter from Kluyveromyces lactis
Devices to JEN1 and DLD promoters characterization:
- EYFP regulated by lactate responsive promoter (JEN1)
- EYFP regulated by lactate responsive promoter (DLD)
- EYFP regulated by constitutive promoter Adh1
Killing mechanism
Parts:
- Lysozyme from Gallus gallus
Devices to Lysozyme characterization:
- Lysozyme constitutive expression
- Lysozyme expression in response to lactate (DLD promoter)
- 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.
