“…This system most likely was already in balance despite of the high solid loading of 15% TS, showing a methane yield of 240 NmL/g VS in the control (Table 1). This is comparable with other values reported previously for AD of PW [3,41,42]. Addition of inhibitors except in the case of car-3-ene, resulted in lower methane yields than that obtained from only PW (Table 1).…”

Effects of antimicrobial compounds on dry anaerobic digestion (dry-AD) processes were investigated. Four compounds with known inhibition effects on traditional wet digestion, i.e. car-3-ene, hexanal, 1-octanol and phenol were selected and investigated at concentrations of 0.005%, 0.05% and 0.5%. Food waste (FW) and Paper waste (PW) were used as model substrates, all assays were running with the substrate to inoculum ratio of 1:1 (VS basis) corresponding to 15% TS in reactors. Generally, increasing concentrations of inhibitors resulted in decreasing methane yields with a few exceptions; in all these specific cases, long, lag phase periods (60 days) were observed. These adaptation periods made possible for the microbial systems to acclimatize to otherwise not preferred conditions leading to higher methane yields. Comparing the effects of the four different groups, phenols had the highest inhibitory effects, with no methane production at the highest amount added, while the lowest effects were obtained in cases of car-3-ene. Furthermore, the results showed that adding inhibitors up to a certain concentrations can repair the balance in AD process, slowing down the degradation steps, hence making it possible for the methanogens to produce a higher amount of methane. This phenomenon was not observed in case of PW, which is already a slow degradable substrate in its nature.

“…This could be the possible reason for not recommending sole PW for acidication. 30 Sole FW hydrolysis was noticed to rapidly increase up to 66% with highest production of sCOD 28 g L À1 . On the other hand, pH rapidly dropped to reach the lowest value, 4.2, during the rst 60 h. Acidication efficiency started from 40%, which was highest.…”

“…The biomethane yield was 0.31 N L CH 4 /g VS and the dominant phylum was Firmicutes, Bacteroidetes under mesophilic conditions. 77 Proteobacteria can utilize various compounds as a carbon source and can be found in the digestate of piggery wastewater and activated sludge at 25-35°C and pH 7.0-9.0. 78 In contrary, anaerobic co-digestion (AcoD) of wheat straw and food waste showed high biomethane yield and dominance of Pseudomonas, Clostridium III, and acetoclastic Methanosarcina in thermophilic reactors.…”

Lignocellulosic biomass is a highly available and suitable candidate for biogas/biomethane production. However, high concentration of recalcitrant lignin is the major obstacle in successful anaerobic digestion (AD). The main aim of this review is to highlight the applications and challenges of lignocellulosic biomass in AD from the recent reports. Potential approaches to improve instabilities in mesophilic AD process (such as microbial communities' development, co-digestion, biofilm carrier's addition, and essential nutrients supplement) were also reported. This review goes one more step deeper to discuss the key microbes involved in lignocellulosic biomass degradation. Biofilm carriers provide attached growth systems for microbes in AD and acts as redox mediators to accelerate the biotransformation of recalcitrant pollutants. Addition of nanoparticles (NPs) stimulate Firmicutes, Bacteroidetes, Methanosaeta, Methanobacterium, and Methanosarcina population which further improve biomethanation. The comprehensive study of these proposed strategies and microbial stimulation through additives would make the lignocellulosic biomethanation more feasible.
