This is an interesting finding that could mean a lot for all who produce
CO2 by fermentation.

Another possibility is that there could be some bacteria in there with the
yeast, and that these bacteria can break down the starch in the flour to
simple sugars.  The yeast could then use the sugars, and undoubtedly the
bacteria are using them also in the respiration process.
