Talk:Ethanol fermentation

message: Why is there a forecast for ethanol production included?  This sort of thing is usually not included in wikipedia articles, and it seems weirdly out of place.  I wasn't aware that forecasting was considered appropriate for an article.  I'm no wikiexpert but I wanted to throw this out there.

message: Today I have, I hope, improved organization and clarity. The article still needs the details indicated in the comments above. Karl Hahn (T) (C) 20:08, 23 September 2007 (UTC)
thread_title: Agreeing with the above comment

message: It appears that one of the formulae is wrong, I would change it myself, but I'm not too sure whether I am just confused.
::CH3CHO + NADH → C2H5OH + NAD+
Is there not one more H on the right than the left?
Looking at the German wikipedia page, it seems that should be:
::CH3CHO + NADH+H+ → C2H5OH + NAD+
This makes rather more sense: it does also beg the question: where does the first H+ come from? - but I guess I'll have to read up on that.  —Preceding unsigned comment added by Divinenephron (talk • contribs) 14:36, 7 September 2008 (UTC)
thread_title:  Incorrect formula? 

message: The introduction to the article is incorrect in reference to yeast using fermentation in low oxygen conditions. Low oxygen conditions do indeed force ethanol production, but yeast will produce ethanol even in the presence of abundant oxygen and glucose. Respiration, the more efficient energy process that uses oxygen and the electron transport chain, is triggered at very low glucose levels.

thread_title: Fermentation is not respiration

message: In the section about effect of oxygen, there is a phrase starting “Our studies ...”. This indicates that it is not commonly accepted. I`m not an expert and don`t know if this is realy the case. At least it should be rephrased and a reference should be added.  — Preceding unsigned comment added by 188.120.81.228 (talk) 14:01, 28 March 2013 (UTC)
thread_title:  Effect of the concentration of ethanol 

message: The section "Microbes used in ethanol fermentation" references Yeast, Zymomonas mobilis, and something referred to as "schizosaaharomyces". I believe this is a mis-spelling of the genus Schizosaccharomyces, which contains the species Schizosaccharomyces pombe (a type of microbe used in ethanol fermentation). However, Schizosaccharomyces pombe is a species of yeast, which is already included in the list "Microbes used in ethanol fermentation". Can someone who knows how to do this either actually insert the link to the wikipedia page for Schizosaccharomyces pombe, or just delete that item of the list altogether for redundancy? 68.98.234.237 (talk) 02:21, 1 July 2014 (UTC)

message: "Ethanol fermentation causes bread dough to rise. Yeast organisms consume sugars in the dough and produce ethanol and carbon dioxide as waste products. The carbon dioxide forms bubbles in the dough, expanding it into something of a foam. Nearly all the ethanol evaporates from the dough when the bread is baked."
Why isn't there a warning that bread production also produces alcohol and contributes via CO2-release to global warming?

thread_title:  Unbalanced formula 

message: Ethanol fermentation from pyruvate is a 2 step process.
Step 1 Decarboxylation by pyruvate decarboxylase
CH3COCOO- + H+ (pyruvate) → CH3CHO (acetaldehyde) + CO2
Step 2 Dehydrogenation by alcohol dehydrogenase
CH3CHO (acetaldehyde) + NADH + H+ → CH3CH2OH (ethanol) + NAD+
It is not correct to state that acetic acid (CH3COOH) is an intermediate product. 2001:569:5822:9500:743B:475D:D8A1:7218 (talk) 04:36, 12 March 2024 (UTC)
