Anaerobic digestion is a biotechnology that can be used to convert various biodegradable organic materials into methane-rich biogas fuel. The anaerobic digestion of municipal solid waste and sewage sludge is a process that has become a promising technology in waste management throughout the world .Digestion occurs in a four-step process: hydrolysis, acidogenesis, acetogenesis and methanogenesis...

BACKGROUND This study aims to chemically characterize thin stillage derived from lignocellulosic biomass distillation residues in terms of organic strength, nutrient, and mineral content. The feasibility of performing anaerobic digestion on these stillages at mesophilic (40 °C) and thermophilic (55 °C) temperatures to produce methane was demonstrated. The microbial communities involved were fur...

In this study, predominant bacterial and archaeal populations their roles during anaerobic mono-digestion of food waste (FW) co-digestion FW with straw pellets (SP) at thermophilic temperature (53 ± 1 °C) were assessed by Next Generation Sequencing (NGS) analysis organic loading rates (OLRs) 3.0 7.0 gVS/L/d. Depending on the seed; results revealed that Firmicutes, Bacteroidetes, Proteobacteria ...

Combined anaerobic–aerobic sludge digestion has been demonstrated as a valid technological solution to improve the sludge stabilization process, in terms of solid reduction and sludge dewaterability properties. In this study, we investigated the fate of all nitrogen species (ammonia, nitrites, nitrates) in the sequential digestion process when the post-aerobic step is operated with intermittent...
