Russell and Strobel (1989) indicated in vitro and in vivo experiments that monensin decreases CH4 production by 30 %, but methanogenic bacteria are not particularly sensitive to ionophores.
With regard to the dynamics of methanogenic bacteria population throughout AD, as depicted in Figure 3, and presence of Desulfovibrionales at the same time point, a competitive interaction for substrate might take place between two types of anaerobic microorganisms [77, 78].
The rate limiting step in vegetable wastes is by methanogenesis rather than by hydrolysis because methanogenic bacteria take long mass doubling time of 3-4 days in anaerobic reactors.
"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."
Different Ks Values for Hydrogen of Methanogenic Bacteria and Sulfate Reducing Bacteria: An Explanation for the Apparent Inhibition of Methanogenesis by Sulfate.
The physiology and ecology of sulfate- reducing bacteria, methanogenic bacteria, hyperthermophiles, and fermentative and chemolithotrophic bacteria are covered.
If the bacteria run out of sulfate, methanogenic bacteria take over as the dominant metabolic force, said Kirk.
The soil Eh of treatment FFE was very low and in the active range of methanogenic bacteria throughout the period of flooding.
In any given sample, therefore, one cannot preclude the possible presence of methanogenic bacteria.
The detection of methanogenic bacteria, however, does not depend on culture techniques.
