Ah, thanks for that organikum.
One do a new batch using standard yeast.
Few questions.. ( I have UTFSE and read most related pdfs' but SWIM can just not find these answers )
1.Has a definitive benzaldehyde concentration been found yet? SWIM would like to make a nice little ratio for scalingĀ up, in the form of water : gms yeast : sugar: benzaldeyhde : (optional acetaldehyde)
2.Will distilling the ethanol out or boiling the broth down for ease of work ruin the l-pac? I think i read somewhere that high heat possibly destroys the l-pac or makes it racemize, but that might just be heat in basic conditions.
3.A lot of people are talking about introducing sterile air into the medium. Should this be done only when the yeast is first introduced to aid with multiplication, or is oxygen added periodically during the anerobic fermentation phase?
If anyone can help out with these, i'll stfu.
