Summary: This study evaluates the methane production potential of pig slurry anaerobic digestion using two different substrate to inoculum ratios (SIR 0.65 and 1) and compares it with theoretical predictions. The results show that a higher SIR of 1 produced more biogas with higher methane content compared to a lower SIR of 0.65, with an SMP of 0.568 NL CH4/g VS and an average methane content of 83% achieved in the experiment. The estimated value presented a deviation of just 2.96% during the assay with a SIR of 1.

Summary: This study evaluated the anaerobic digestion of agricultural waste, manure, and slaughterhouse residues from species typical of the Andes region, such as llama, vicuna, and guinea pig; quinoa, amaranth, and wheat straw. The highest methane production rates were achieved for flame manure and quinoa straw at an RSI of 1:2, with significant increases compared to an RSI of 1:1. The modified Gompertz model proved to be the best fit for performance analysis, with a constant difference of 7.06% between experimental and predicted values.

Summary: This research evaluated the anaerobic digestion of llama and dromedary dungs in batch mode at mesophilic temperature. The study found that trampled llama dung had a higher methane yield compared to raw llama and dromedary dungs. Trampled llama dung was determined to be the best substrate for methane production due to its high volatile solids content, nitrogen content, and appropriate C/N ratio. The experimental data aligns with both first-order kinetic and transference function mathematical models.

Summary: The anaerobic digestion process is widely used for organic waste treatment, with Biochemical Methane Potential assays being the most commonly applied method for evaluating suitable substrates. This paper provides a review of anaerobic feedstocks, BMP methodologies, experimental conditions, and results from 2008 to 2023. The study found a wide range of anaerobic feedstocks, characterized by different parameters such as TS, VS, COD, and pH. Despite efforts to standardize the BMP method, there are still gaps in experimental conditions and determination of specific methane production, posing challenges for study comparisons.

Summary: This study found that the biochemical methane potential of water hyacinth and municipal solid waste in Mexico City could be effectively managed through anaerobic digestion and anaerobic codigestion processes. The substrate-to-inoculum ratio played a significant role in volatile solids degradation. Anaerobic digestion of municipal solid waste with a S:I ratio of 1:1 produced more methane than anaerobic codigestion, but the difference was not statistically significant. Overall, the research highlighted the potential of using anaerobic digestion for renewable energy production and addressing the issues associated with water hyacinth, municipal solid waste, and leachate.

Summary: This study aims to investigate the methane generation potential of different samples from the dark acid fermentation of sewage sludge and the effect of high ammonia concentrations in poultry manure when used as a co-substrate. Results show that the addition of poultry manure improves methane production and the mixture of sewage sludge, wine vinasse, and poultry manure has the highest purification percentages and methane yield. The presence of poultry manure also increases microbial concentration during the BMP test.

Summary: This study introduces a novel combined pretreatment approach involving steam explosion and GVL/water delignification to improve the enzymatic saccharification efficiency of corn stalk. The method effectively removes lignin and enhances glucan content in the solid material, leading to significantly increased glucose concentration during high-solid loading enzymatic hydrolysis with relatively low cellulase addition. The combined pretreatment shows promise for green lignocellulosic biorefinery by fractionating corn stalk and producing a glucan-enriched solid with enhanced enzymatic digestibility.

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.
