In the past decades, considerable attention has been directed toward anaerobic digestion
(AD), which is an effective biological process for converting diverse organic wastes into …

Although considerable progress has been made in recent years regarding the classification
of bacteria assigned to the phylum Bacteroidetes, there remains a need to further clarify …

Propionate is a key intermediate in anaerobic digestion processes and often accumulates in
association with perturbations, such as elevated levels of ammonia. Under such conditions …

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

High-load reactors face a significant challenge with fatty acid accumulation. Although
injecting acidogenic gas (H 2 and CO 2) into methanogenic reactors improves biogas …

The growing applications of CuO nanoparticles (NPs) in industrial and agriculture has
increased their concentrations in wastewater and subsequently accumulated in waste …

In the past decade, the characterisation of the microbial community in anaerobic digestion
was primarily done by using high-throughput short-read amplicon sequencing. However, the …

Two-stage anaerobic digestion (AD) system is an efficient technology; however, organic
loading rate (OLR), a critical design and process parameter, influences the performance and …

Improving hydrolysis and acidogenesis through thermophilic and hyperthermophilic
temperatures is critical for enhancing the anaerobic decomposition of organic waste like pig …

Biological hydrogen methanation (BHM) is a biocatalytic process for biogas upgrading.
Integrating ex-situ BHM processes into biogas facilities has the advantage of using …
