With the combined action of the aerobic and the facultative layers effectively removing the excess fermentation products, the methanogenic bacteria in the anaerobic layer are relieved from inhibition.

It was found that, the methanogenic bacteria diversity was slightly different among treatments which led to 7 separate bands of DNA morphology across all lanes of the gel.
Lower methane production at high concentrate level may also be attributed to shift in VFA proportions in favor of propionate, and inhibition of methanogenic bacteria and rumen ciliates (Van Nevel and Demeyer, 1988; Van Kessel and Russell, 1996).
Low hydrogen concentration is normally observed in the rumen because most of hydrogen produced from fermentation is used for the reduction of CO2 to CH4 by methanogenic bacteria (Hungate et al.
