Summary: Methanogenic archaea are important but often ignored in studies of human and animal intestinal microbiota. This research focused on improving the quantification of methanogens using qPCR, by refining the protocol and increasing the specificity and sensitivity of the assay. The results showed increased detection range and successful validation parameters, allowing for improved detection and quantification of methanogens in stool samples, such as chicken droppings in this study.

Summary: The cultivation and investigation of strictly anaerobic microorganisms is important in the fields of anaerobic microbial physiology, microbiology, and biotechnology. Anaerobic cultivation methods differ from classic microbiological techniques in terms of instrument requirements and challenges. Anaerobic microbiological methods play a crucial role in the isolation and characterization of new species, physiological examination, anaerobic biotechnological applications, and medical indications.

Summary: Biogas upgrading is a process to separate methane from carbon dioxide and impurities in order to increase its purity and combustion efficiency. Conventional technologies have issues, while hydrogenotrophs-based biological upgrading attracts attention due to its simplicity and technological potential.

Summary: This study evaluates the impact of Zero-Valent Iron (ZVI) on the anaerobic digestion of cheese whey and finds that it can improve methane yield and COD removal. The reactors with ZVI maintain a lower VFA/ALK ratio compared to the control group. ZVI mainly affects methanogenesis and acidogenesis, not solubilization/hydrolysis. Higher concentration ZVI performs better than scrap ZVI.

Summary: This study investigates the effects of bioaugmentation on the co-digestion of cheese whey and manure in a continuous stirred tank reactor under in-situ biomethanation operations. The addition of Methanoculleus bourgensis in the mesophilic reactor resulted in a stable biomethanation process and increased methane production rate. On the other hand, the addition of Methanothermobacter thermautotrophicus in the thermophilic reactor did not improve biogas upgrading performance.

Summary: This study investigates the potential of waste cooking oils (WCOs) for biogas production in anaerobic digestion (AD). The results show that the biogas production from WCOs is over 5 times higher compared to the control group. The study also analyzes the activity of microbial enzymes and the microbial community structure.

Summary: This study focuses on optimizing the detection procedures of methanogenic archaea DNA, including the DNA isolation step. Through experiments on chicken droppings, it was found that a combination of a specific kit, ultrasonic probe sonication for 2 minutes, and enzymatic pretreatment can greatly improve the efficiency of methanogenic archaea DNA extraction. This optimized protocol is suitable for quantitative microbial analysis by real-time PCR, while also providing optimal protection for DNA extracted from bacteria susceptible to enzymatic lysis.

Summary: The study focused on utilizing waste coal washery rejects to produce biogenic methane, with the best anaerobic slurry producing around 55.7% methane. Cow dung and distillery anaerobic sludge showed similar methane production to coal mine enriched inoculum. The study suggested that these consortiums can effectively convert coal washery rejects into methane.

Summary: Ex-situ biomethanation in a biotrickling filter is a technology that converts CO2 to CH4 using hydrogenotrophic methanogens in a biofilm. Nutrient supply, particularly ammonium and iron, is crucial for maintaining an active biofilm. Thoroughly wetting the biofilm with nutrient media periodically is essential for stable operation, despite temporary reductions in conversion rates.
