Help : ethanol productivity of yeast and pH control in fermentation
Posted 19 October 2011 - 08:00 AM
so if we want to test the ethanol productivity of yeast , we should not monitor pH and let pH change by its course so that we can use GC method and find out the concentration of ethanol produced.
but my colleague said the ethanol can be still detected as it is formed as CH3Ch2ONa in the broth by using the GC. so we can still control pH at 7 and detect the ethanol productivity of yeast in fermentation.
which one is correct ?
if you know, please share your thought. it really confuses me.
