Lignocellulosic substrate co-digestion as a pre-treatment step to anaerobic digestion increases the viability of using agro-industry waste for biogas production. This study aimed to assess proportions of co-digestion of swine manure and poultry litter for greater methane production, in addition to analyzing the effect of microbial inoculum enrichment on biodigestion. After co-digestions were prepared, the fractions (solid and liquid) were separated, and the liquid was used in the tests. Methane production potential tests were assessed using the Doehlert experimental design in co-digestions of swine manure and poultry litter at 0%, 10%, 20%, 30% and 40% (m/m). The other variable studied was the amount of inoculum added (ISR) at levels of 2, 1.25 and 0.5. The highest methane production values (286–284 NL kgVS-1) were obtained in co-digestions between 10% and 20% (m/m) of poultry litter, which present total solids compatible with using covered lagoon and CSTR model biodigesters. A 34% increase was obtained in the microbial inoculum enrichment study, when compared to standard inoculum use. The co-digestion phase separation procedure developed in this study increased the feasibility of implementing this technology as an alternative to biogas production in commonly used biodigestion systems.

“…Anaerobic biogas production is a four-stage microbial process consisting of hydrolysis, acidogenesis, acetogenesis/ dehydrogenation, and methanation, of which hydrolysis is considered to be the rate-limiting step (Nguyen et al 2015;Weiland 2010;Feki et al 2015;Grübel and Suschka 2015). Biogas-producing bacteria mainly belong to phyla Proteobacteria, Firmicutes, and Bacteroidetes, while the most common archaeal bacteria related to methane production belong to orders Methanomicrobiales, Methanosarcinales, Thermoplasmatales, and Methanobacteriales (Goswami et al 2016;Han et al 2019). The final biogas product consists mainly of methane (60-70% in maximum) and carbon dioxide (Appels et al 2008).…”

Biogas production from sewage sludge volatile solids (VS) by anaerobic digestion slows down towards the end of the process, among inhibitory factors being pH increase upon ammonia accumulation, poorly digestible biomaterials, and high fixed solid (FS) content. The possibility of concentrating the digested sludge VS (41.7-56.6% on a dry weight basis) by surface and bottom layer separation with biogas post-production was studied. Furthermore, the potential to recycle concentrated VS and digested sludge back to the process after adjusting pH 7.0 to optimal for biogas-producing microbes and after acid, alkali, thermal, and sonolytic treatments was examined. In general, pH 7.0 control alone improved biogas production from the recycled digested sludge the most. An equally good improvement in biogas production was achieved by recycling the digested sludge, which had been heated until ammonia had evaporated and the pH dropped to 7.0 (1-2 h, 75°C), and at the same time, VS was degraded. The biogas production from the sonicated and recycled sludge was almost as good as from the pH-adjusted, or heat-treated recycled sludge. After the acid and base treatments of the digested sludge, the recycled sludge yielded often the lowest biogas volume, as the added chemicals increased the FS concentration, which proved to be a more important inhibitory factor than poorly degradable VS. The high FS content significantly reduced the benefits of the treatments. By separating the surface and bottom layers with biogas post-production, the surface layer of VS was concentrated to 51.6-61.8%, while different compositions of the layers affected the biogas production.

“…Relatively permanent representatives of methanogenic archaea in anaerobic bioreactors are representatives of the genus Methanothrix [91][92][93]. In laboratory or pilot anaerobic reactors, which were filled with various substrates such as breeding wastewater, slaughterhouse wastewater or a mixture of different residues from meat processing and livestock farming, representatives of the genus Methanothrix prevaled in methanogenic community in bioreactors [43,63,92,[94][95][96].…”

Over the past decades, anaerobic biotechnology is commonly used for treating high-strength wastewaters from different industries. This biotechnology depends on interactions and co-operation between microorganisms in the anaerobic environment where many pollutants’ transformation to energy-rich biogas occurs. Properties of wastewater vary across industries and significantly affect microbiome composition in the anaerobic reactor. Methanogenic archaea play a crucial role during anaerobic wastewater treatment. The most abundant acetoclastic methanogens in the anaerobic reactors for industrial wastewater treatment are Methanosarcina sp. and Methanotrix sp. Hydrogenotrophic representatives of methanogens presented in the anaerobic reactors are characterized by a wide species diversity. Methanoculleus sp., Methanobacterium sp. and Methanospirillum sp. prevailed in this group. This work summarizes the relation of industrial wastewater composition and methanogen microbial communities present in different reactors treating these wastewaters.
