In the third stage the generation of C[H.sub.4] by methanogenic
bacteria by breaking acids in C[H.sub.4] and C[O.sub.2] or by the reduction of C[O.sub.2] and [H.sub.2] occurs.
(1992) [H.sub.2]-forming methylenetetrahydro-methanopterin dehydrogenase, a novel type of hydrogenase without iron-sulfur clusters in methanogenic
Steady Phase (1 year to 5 years) - The final stage of decomposition involves methanogensis.
Influence of the initial substrate to microorganisms concentration ratio on the methanogenic
"We were surprised that we did not find methanogenic
bacteria that produce methane at Lost Hammer," Whyte said, "but we did find other very unique anaerobic organisms - organisms that survive by essentially eating methane and probably breathing sulfate instead of oxygen."
y Beaudet R.: "Removal of phenolic compounds from a petrochemical effluent with a methanogenic
This composition indicated that mainly methanogenic
mineralization of organic matter was taking place in the ASBR.
bacteria metabolize these compounds into a combination of methane-rich gas and an odorless phosphorus- and nitrogen-laden slurry, which makes excellent fertilizer.
The physiology and ecology of sulfate- reducing bacteria, methanogenic
bacteria, hyperthermophiles, and fermentative and chemolithotrophic bacteria are covered.
