Background Microorganisms in biogas reactors are essential for degradation of organic
matter and methane production. However, a comprehensive genome-centric comparison, …

Background Carbon fixation through biological methanation has emerged as a promising
technology to produce renewable energy in the context of the circular economy. The anaerobic …

Biogas is extensively promoted as a promising renewable energy. Therefore, the search of
appropriate co-substrates has come into focus. In this study, we examined the potential of …

Anaerobic digestion is a key biological process for renewable energy, yet the mechanistic
knowledge on its hidden microbial dynamics is still limited. The present work charted the …

Four different types of ceramic gas distributors (Al 2 O 3 of 1.2 μm and SiC of 0.5, 7 and 14
μm) were evaluated to increase biomethane formation during ex-situ biogas upgrading …

Background The expansion of renewable energy produced by windmills and photovoltaic
panels has generated a considerable electricity surplus, which can be utilized in water …

Biogas upgrading processes by in-situ hydrogen (H 2 ) injection are still challenging and
could benefit from a mathematical model to predict system performance. Therefore, a previous …

A mixture of piggery slurry and algal species (mainly composed of Nannochloropsis limnetica),
grown in municipal wastewater, were used as substrates for biogas production. Mono- …

Temperature is one of the most crucial state variables in industrial process control, which is
particularly true for the biochemical conversion of biomass, as in anaerobic digestion. …
