Plant waste biomass is the most abundant renewable energy resource on Earth. The main problem with utilising this biomass in anaerobic digestion is the long and costly stage of degrading its complex structure into simple compounds. One of the promising solutions to this problem is the application of fungi of the genus, which show a high capacity to produce hydrolytic enzymes capable of degrading lignocellulosic biomass before anaerobic digestion. This article discusses the structure of plant waste biomass and the problems resulting from its structure in the digestion process. It presents the methods of pre-treatment of lignocellulose with a particular focus on biological solutions. Based on the latest research findings, key parameters related to the application of sp. as a pre-treatment method are discussed. In addition, the possibility of using the digestate from agricultural biogas plants as a carrier for the multiplication of the sp. fungi, which are widely used in many industries, is discussed.

Microbial Fuel Cells (MFCs) are innovative environmental engineering systems that harness the metabolic activities of microbial communities to convert chemical energy in waste into electrical energy. However, MFC performance optimization remains challenging due to limited understanding of microbial metabolic mechanisms, particularly with complex substrates under realistic environmental conditions. This study investigated the effects of substrate complexity (acetate vs.

Anaerobic digestion is a crucial process in wastewater treatment, renowned for its sustainable biogas production capabilities and the simultaneous reduction of environmental pollution. However, dysregulation of vital biological processes and pathways can lead to reduced efficiency and suboptimal biogas output, which can be seen through low counts per million of sequences related to three critical control points for methane synthesis. Namely, tetrahydromethanopterin S-methyltransferase (MTR), methyl-coenzyme reductase M (MCR), and CoB/CoM heterodisulfide oxidoreductase (HDR) are the last reactions that must occur.

This work evaluated the effect of zero-valent iron (ZVI) particle size (150 μm-100 nm) on the performance of food waste anaerobic digestion (AD) under various acid stress conditions. The results indicated that ZVI significantly improved the AD performance, ensuring successful CH production even under high acid stress. However, the extent of this promoting effect was highly dependent on the particle size.

Anaerobic digestion (AD), which relies on a complex microbial consortium for efficient biogas generation, is a promising avenue for renewable energy production and organic waste treatment. However, understanding and optimising AD processes are challenging because of the intricate interactions within microbial communities and the impact of volatile fatty acids (VFAs) on biogas production. To address these challenges, this study proposes the application of graph convolutional networks (GCNs) to comprehensively model AD processes.
