Outstanding, my access to academic references is not what it once was!

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.


"Enhancement of methanogenesis by traces of oxygen in bacterial digestion of
biomass", S.J. Pirt, Y.K. Lee. FEMS Microbiology Letters, Volume 18, Issues
1-2, April 1983, Pages 61-63?
