“…Although at higher temperature that is thermophilic temperature, anaerobic digestion is reduced as well as the dewatering properties of the digested feedstock. 49,50 More also, studies show that a correlation exist between temperature and HRT as well as kinetic rate constant. Biogas production peaks are obtained at different days for different temperatures.…”

The authors reviewed the future prospects and previous studies on anaerobic digestion technology for biogas production and highlight the solutions to problems relating to construction and maintenance of biogas digesters, which can now be accessed in a single paper. It is the aim of the review to provide insight into the use, process and application of anaerobic digestion as an appropriate technology for biogas production from peer reviewed literature. Recent studies have shown that the microbial communities and metabolic pathways involves in anaerobic digestion are influenced by temperature. Their metabolic activities increase significantly with increase in temperature. Therefore, the findings of the review reveal that temperature is a major parameter for biogas production due to its influence on metabolic activities involved in anaerobic digestion. Hence, there is the need for insulation as well as external heating to maintain temperature stability and to avoid temperature fluctuations. More also, the anaerobic digestion technology for production of biogas is a viable option that can supplement as well as reduce the usage of non-renewable energy sources such as fossil fuel. The detailed information addressed in this study would increase biogas energy mix as well as mitigating climate change. Therefore, the study recommends the use of biogas as a clean energy for the purpose of power generation, cooking and heating.

“…Methanomicrobiales populations, and thus hydrogenotrophic methanogensis, have been reported to play an important role in low-temperature anaerobic granular sludge systems and digestion under psychrophilic conditions in a number of studies (McHugh et al, 2004;Connaughton et al, 2006;Zhang et al, 2012;Gunnigle et al, 2015;Tian et al, 2018). However, several authors also described an increase in acetoclastic methanogenesis and a high abundance of Methanosarcinales in anaerobic digestion under psycrophilic conditions (O'Reilly et al, 2009;Penfield, 2017;Zhang et al, 2018).…”

“…Bialek et al used dairy farm wastewater as raw material to carry out low‐temperature biogas fermentation at 10°C and reported that Clostridium aminobutyricum was the most abundant bacterial species. Tian et al conducted a study on pig manure in a 15°C batch biogas production system and found Clostridium sartagoforme (decomposes cellulose and chitin) was dominant at the hydrolysis stage. Clostridium species thus seem to be dominant when the raw material is rich in macromolecular carbohydrates such as cellulose and hemicellulose.…”

“…This revealed that hydrogen‐consuming methanogens were gradually replaced by acetic acid‐consuming methanogens as the fermentation temperature declined. Tian et al used pig manure as raw material to carry out low‐temperature biogas fermentation at 15°C and found that Methanobacterium formicicum which can convert CO 2 and H 2 into methane in the methanogenesis stage was the most abundant archaeal species. Xing et al fermented algae as raw material at 15°C and found that hydrogen‐consuming Methanomicrobiales and Methanobacteriaceae were dominant.…”

The main objective of this study was to establish the metabolic pathway of a biogas fermentation system active at low temperature, and to describe the bacterial and archaeal methanogenic species responsible. A biogas fermentation inoculum adapted to be active at 9°C was used in a 10‐L batch‐type temperature‐controlled fermentor, using pig manure as the raw material. Fermentation at 9°C was followed for 120 days. A combination of nonbiological and biological factors was analyzed. Species were identified from OTU analysis based on 16S rDNA amplicon sequencing, and correlation analysis was used to study the effect of nonbiological factors, bacterial communities, and archaea communities. Biogas production was most effective between days 50 and 90, where gas production was above 0.70 L/d and the CH4 yield was above 0.36 L/g‐volatile solid. The relative abundance of the first dominant bacterial OTU with 99% identity to Clostridium cellulovorans varied between 16.17% and 27.30%. These bacteria typically degrade cellulose and hemicellulose. The second dominant bacterial OTU (relative abundance 15.23%‐27.15%) was 99% identical to Terrisporobacter petrolearius, a typical fermentative species. The most abundant (4.15%‐37.14%) archaeal OTU was 98% identical to Methanocorpusculum sinense, which is a typical hydrogenotrophic methanogen. A low‐temperature biogas metabolic pathway was constructed, based on abundant bacterial and methanogen OTUs. The most suitable metabolic pathway describes that hydrogen is produced by one part of the community and then used to reduce the produced carbon dioxide into CH4; this seems to be the major pathway by which biogas is produced under low‐temperature conditions.
