This study investigates the effect of the organic loading rate (OLR) increase from 1.0 to 3.5 g VS L(-1) day(-1) at constant hydraulic retention time (HRT) of 35 days on anaerobic reactors' performance and microbial diversity during mesophilic anaerobic digestion of ammonium-rich chicken wastes in the absence/presence of zeolite. The effects of anaerobic process parameters on microbial community structure and dynamics were evaluated using a 16S ribosomal RNA gene-based pyrosequencing approach. Maximum 12 % of the total ammonia nitrogen (TAN) was efficiently removed by zeolite in the fixed zeolite reactor (day 87). In addition, volatile fatty acids (VFA) in the fixed zeolite reactor accumulated in lower concentrations at high OLR of 3.2-3.5 g VS L(-1) day(-1). Microbial communities in the fixed zeolite reactor and reactor without zeolite were dominated by various members of Bacteroidales and Methanobacterium sp. at moderate TAN and VFA levels. The increase of the OLR accompanied by TAN and VFA accumulation and increase in pH led to the predominance of representatives of the family Erysipelotrichaceae and genera Clostridium and Methanosarcina. Methanosarcina sp. reached relative abundances of 94 and 57 % in the fixed zeolite reactor and reactor without zeolite at the end of the experimental period, respectively. In addition, the diminution of Synergistaceae and Crenarchaeota and increase in the abundance of Acholeplasmataceae in parallel with the increase of TAN, VFA, and pH values were observed.

“…50 Concerning the dimension of internal pores, materials which exhibited micro/mesoporous structures performed favourably in fermentation. 41,42 It was found that cell growth on these carriers were 11.7-34.0% greater than that obtained from the free cells. Similarly, the productions of succinic acid with immobilised cells were found at 6.8-26.0% higher than that with the free cells.…”

“…It is worthy of note that larger pore volume implies higher capacity to hold a substance of interest. 42 The average pore size of CSAC (21.2Å) was much greater than that of CAC (4.5Å) with nearly ve-fold difference. In this regard, three types of internal pore are associated with sorbent materials, which are: (i) micropore (diameter < 2 nm); (ii) mesopore (diameter ¼ 2-50 nm), and (iii) macropore (diameter > 50 nm).…”

“…The factors of excellent surface area that allows copious capacity for cell retention, and high EPS content which promotes irreversible cell attachment will result in a good succinic acid production performance. 42 Hence, the extent of cell growth on different porous supports appeared to be directly inuenced by a reduced zeta potential and a highly porous structure. 41 3.3.1 Bacterial observation on CSAC.…”

1,1,1-Trichloroethane (1,1,1-TCA), a dense non-aqueous phase liquid (DNAPL), is relatively slow to remediate naturally; combination of zero-valent iron and immobilized microorganism is a potential means to accelerate DNAPL biodegradation. We first adopted high density luffa sponge (HDLS) as immobilized microorganism carrier. The experimental results demonstrated that (1) the supernatant liquid microorganisms were the optimal immobilized microorganisms for HDLS and (2) the combination of zero-valent iron and immobilized microorganisms accelerated 1,1,1-TCA transformation. Furthermore, in the long-term remediation process, anaerobic microorganisms produced reductant HS which was beneficial to zero-valent iron PRBs. Through further study of the microbial community, we found that majority of the sulfate-reducing bacteria (SRB) perfectly adapted to the process of 1,1,1-TCA co-metabolism dechlorination. Desulfobulbus and Desulfococcus potentially were the special SRB that contributed significantly to TCA co-metabolism. Additionally, 1,1,1-TCA induced the generation of new SRB and stimulated the growth of majority of dominating methanogens. The results indicated that they played a constructive role in accelerating the dechlorination of 1,1,1-TCA, reduction of sulfate, and improving the production of CH. Consequently, combination of zero-valent iron and immobilized microorganisms for remediating groundwater by contaminated 1,1,1-TCA is a sustainable and green remediation technology. Especially for groundwater of SO type contaminated by 1,1,1-TCA, in the long-term course of combination degradation, cyclic utilization of HS to prolong the service life of zero-valent iron PRBs. H and CH generated to capture as potential energy resource. Based on this, a tentative reaction mechanism for Fe biodegradation of 1,1,1-TCA was proposed.
