This paper review is aiming to comprehensively identify and appraise the current available
knowledge on microbial composition and microbial dynamics in anaerobic digestion with …

Anaerobic digestion (AD) technology is limited by low-temperature conditions preventing the
adoption of simple, unheated digesters during cold periods. Decrease in temperature has a …

Biomethane as a sustainable, alternative, and carbon-neutral renewable energy source to
fossil fuels is highly needed to alleviate the global energy crisis and climate change. The …

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

Increasing global demand for green energy has necessitated more research interest in
anaerobic digestion. Due to the dual benefits of anaerobic digestion, in organic waste …

Ammonia released from the degradation of protein and/or urea usually leads to suboptimal
anaerobic digestion (AD) when N-rich organic waste is used. However, the insights behind …

Using anaerobic membrane bioreactors (AnMBRs) to treat swine wastewater is an effective
method to recover bioenergy. However, due to the inhibitory effect of high concentrations of …

Biogas upgrading is an emerging technology offering unique opportunities for further
exploitation of biomethane as fuel for vehicles or direct injection into the gas grid, expanding …

It is known that the presence of sulfate decreases the methane yield in the anaerobic
digestion systems. Sulfate-reducing bacteria can convert sulfate to hydrogen sulfide …
