What about enzimes and co-enzimes stimulation with available
chemical oxygen ?</font><br>
There are epxpemriment I could probably trace back regarding
co_digestion of waste sirup made of tamarin fruit and vinasse
which had stressed on the stimulation of enzime<br>

Dear Paul
It was a UK based research project and everything was measured to the nth
degree including gas composition (sure that does not make it fool proof).
The only reason we resorted to a literature search was this it was otherwise
unexplainable. The overall mass balance was the same against the control, it
was just that the rate of biogas conversion was greater. Stimulation was the
only explanation we could envisage, which seemed counterintuitive at the
time, but it was interesting to see that others had reported similar
effects.

Maybe the increased Gas was Carbon Dioxide - did you measure gas quality?
There are a number of things where a small amount is good but too much is
bad.
HOOROO

<pre wrap="">Dear List
Many years ago we found some unexplained stimulation of biogas
production when oxygen had accidentally been introduced into an
anaerobic system. This was as air, and not oxygen in chemical form.
While this should have traditionally been inhibitory to the
methanogens, for some reason, in the specific circumstances prevailing
at the time it was not. At the time we explored this in the literature
and found a paper by Pirt and Lee which indicated recorded stimulation
due to oxygen introduction. If I can track it down I will forward it.
