Kiev methane and methane estate community population structure analysis of qPCR, respectively operation of anaerobic digestion. (Such as hostage perature unit. OLR and surface composition) greatly affects the population Bial and archaea methane are more susceptible to these environmental changes than bacteria 139 so qPCR ysis was used to estimate the population of the capital as well. show concentrations of gene 16S rRNA Fww concentration 16s rRNA gene of all (Table 3) of archaeal 16S rRNA genes in the seeds (of MAD) is 1.52 x 109 copies / mL and increased to 3.52 x 10 copies / mL. (Call me), this increase shows that the microbial balance that was maintained in the reactor and the temperature may increase the type archaeal populations capital increased remarkably with an increase of Fww ratio (. 5.54 x 10 (called LL) 8.29 x 10 (call lll) and 1.15 x 1,010 copies / mL (Run IV), but decreased significantly in the run-volt (2.29 x 10 copies / ml.) of land total. The positive correlation between the stability of the reactor (Fig. 2) and efficiency (Fig. 3). In particular, the production of methane (Table 2), thus increasing the ratio FWW in TAcoD can not. Only But increase the removal of organic material. But also impact positively on the capital with a population of methane, which significantly contributes to the production of methane.
