Summary: Lignocellulosic biomass is a crucial resource for expanding biogas production, and research on pretreatment technologies to enhance biomass conversion is a rapidly growing field. This study analyzed seven different types of lignocellulosic biomass and identified key characteristics for effective pretreatment. A simple ammonia pretreatment was used as a case study and partial least squares regression was employed to model the methane yield and efficiency of the pretreatment. The results showed that lipid, ash, protein, and hemicellulose/lignin content were the most decisive factors in predicting pretreatment efficiency.

Summary: Micro-aeration can promote anaerobic digestion by regulating microbial communities and facilitating the growth of facultative taxa. This enhances methane production and stabilizes the AD process. It also helps remove hydrogen sulfide through oxidation. However, micro-aeration must be carefully controlled to maintain an overall anaerobic environment and minimize oxidative stress on obligate anaerobes, especially methanogens.

Summary: The application of mathematical models as tools and early warning indicators can optimize the anaerobic digestion process in biogas reactors. The Bioconversion Model (BioModel) was evaluated in this study for simulating common perturbation cases caused by fatty acids and ammonia inhibition. The simulations showed good agreement with experimental data on methane productivity and pH, but discrepancies were observed in the prediction of volatile fatty acids' concentrations. Adjustments to the model's kinetic parameters were necessary to improve the prediction accuracy. Overall, the BioModel demonstrated effectiveness in simulating different co-digestion strategies with fatty acid or ammonia presence.

Summary: Three inhibitors, including sodium ionophore III (ETH2120), carbon monoxide (CO), and sodium 2bromoethanesulfonate (BES), were assessed for their impact on CO2 biomethanation in microorganisms from Archaea and Bacteria domains. The study demonstrates that ETH2120 and CO can promote methane production while BES does not, indicating the inactivation of archaea. Methylotrophic methanogenesis from methylamines was the main pathway for methane production, and a slight decrease in acetate production with an increase in CH4 production was observed with the addition of 20 kPa of CO. It should be noted that all compounds had effects on the microbial community composition, although the specific effects on CO2 biomethanation were challenging to observe due to the complexity of the environmental samples used as inoculum.

Summary: The oleaginous microalga Scenedesmus sp. SPP was rapidly immobilized in oleaginous fungal pellets by utilizing their opposite surface charges. The microalgae-fungal (MF) pellets showed higher efficiency in improving the bioremediation of non-sterile secondary effluent compared to mono-culture. By coating the MF pellets with 0.4% chitosan, the removal efficiencies of COD, TN, and TP were significantly enhanced, likely due to better cell retention and nutrient adsorption and assimilation.

Summary: Wastewater from the potato processing industry, protamylasse, can be valorized through the cultivation of microalgae by mixotrophic metabolism. A new two-stage system was developed, where volatile fatty acids (VFA) were produced through anaerobic acidification (AA), and Chlorella sorokiniana was cultivated for valorization of nutrients and organics. This process resulted in high removal efficiencies of phosphorus, nitrate, and ammonia, and the production of microalgal biomass with high protein content.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
