The yeasts of ethanol samples achieved the optimum OD only today.
We induced these samples with the same concentrations used in glucose ones, described yesterday.
Yeast experiments: Methods of analysis
Live Lactococcus dead!
The samples were analyzed by:
I) Aplication of the yeasts culture supernatant in liquid cultures of Lactococcus lactis (the OD of the bacterial culture was monitored for some hours).
II) The glucose samples were also analyzed by inhibition zones formation in solid culture. Unfortunately we have no time to do these tests to the ethanol samples.
