Summary: The study found that when digesting cork boiling wastewater (CBW), the biomethane potential is very low for Ino/CBW ratios of 1:1 and 2:1 compared to other organic substrates using digested sludge as inoculum; however, co-digestion with cow manure showed better biomethane yields.

Summary: This research experimentally investigated the use of food waste and garden waste as substrates for producing thermic and electric energy through a lab bioreactor. A mesophilic continuous stirred-tank reactor (CSTR) was used to support the operational planning of a pilot-scale Plant. The results showed high efficiency of solids removal, stable pH, and a maximum methane yield. The energy potential and composition of the digestate were also evaluated.

Summary: This study explored the feasibility and mechanism of adjusting the inoculum-to-substrate ratio (ISR) to improve the methane production from food waste (FW) with a low carbon/nitrogen (C/N) ratio. The results showed that the maximum methane yield was achieved at a C/N ratio of 11 and an ISR of 10:3. Increasing the ISR promoted methane production by enhancing acetoclastic methanogenesis and the hydrolysis of carbohydrates and proteins.

Summary: The research found that in plateau areas, using temperature change mode for AD treatment of Tibetan food waste can achieve methane yields equivalent to or slightly higher than fixed 35 degrees Celsius treatment. Temperature fluctuations have a minor impact on methane production performance, and at 15 degrees Celsius, the digestion pathway shifts from acetoclastic to hydrogenotrophic.

Summary: The study investigated the biochemical methane potential, biodegradability, and kinetic parameters of goat manure at different inoculum to substrate ratios. Results showed that the biomethane yield was similar among all ISRs and significantly higher than the control group. The biodegradability of goat manure was consistent across different ISRs, with 90% of the yield observed within 31 to 32 days.

Summary: This study comprehensively explored the effects of different substrate to inoculum ratios (S/I) on the kinetic parameters, microbial communities, and metabolic pathways during the anaerobic digestion process of food waste. The results showed that low S/I ratios were favorable for methanogenesis, while high S/I ratios led to irreversible acidification. S/I = 1:3 had the highest methane yield, more apparent microbial cooperation, and the highest abundance of key enzymes involved in the methanogenesis pathway.

Summary: This study aims to generate methane-enriched biogas from unsorted organic municipal solid waste (MSW) using dry anaerobic digestion (DAD). By adjusting various process parameters, it was found that the highest biogas yield could be achieved at 37 degrees C, with a mixed inoculation mode (AS:CM-1:2) and a multilayer inoculum flow pattern.

Summary: This study investigated the effect of substrate-inoculum ratio and fly ash concentration on the anaerobic digestion of winery wastewater. The results showed that a substrate-inoculum ratio of 0.50 g soluble COD/g VSS was the most effective. Among the tested fly ash concentrations, adding 100 mg/L improved methane production by 79%, while 150 mg/L inhibited methane production. Additionally, it was found that fly ash had a similar effect to a system with Fe-EDTA, indicating the bioavailability of Fe in the fly ash.

Summary: Poultry wastes can be used as substrates for biogas production, but the high protein content leads to ammonia inhibition. Different substrates and inoculum sources affect the biochemical methane potential, and increasing the substrate-to-inoculum ratio decreases the hydrolysis constant. Liger is the most suitable inoculum source. Comparing organic laying hen droppings with slaughterhouse waste, slaughterhouse waste is more important in anaerobic digestion due to its high methane yield, especially from viscera. Methane production is affected by increasing ammonia concentrations.

Summary: This study evaluated the impact of different SIR values on the batch anaerobic digestion of cotton textile waste, and found that treated substrate showed higher methane yield and anaerobic degradability compared to untreated substrate. The Gompertz model fitted well with the experimental data, with an R2 value of 0.96-0.99, showing improvement over the first-order kinetic model.

Summary: This study evaluated the suitability of biochar-assisted co-digestion in the anaerobic digestion of food waste and sewage sludge. The results showed that biochar addition played a critical role in stabilizing methane production and caused significant changes in the microbial community composition at higher inoculum and substrate ratios.

Summary: Metagenomics and single-cell genomics have allowed the discovery of uncultured microbes, while single-virus genomics (SVG) has opened new possibilities in viral ecology. The investigation of methodological alternatives and optimization of existing procedures for SVG is crucial for delivering high-quality genomic data. Our study provides insight into different conditions for sequencing viral single-amplified genomes (vSAGs) and highlights the importance of fresh samples for better genome quality data, as well as the sensitivity of novel WGA methods in SVG.

Summary: A study was conducted using a shale GeoBioCell microfluidic testbed to evaluate the impact of sulfate-reducing bacteria (SRB) growth and iron sulfide biominerals on pore reduction and hydraulic resistance in hydraulically fractured shale reservoirs. The experiments showed that the growth of SRB biofilms encrusted with iron sulfides led to complete clogging of the pores, hindering flow in the shale reservoirs.

Summary: This study elucidates the diversity of viruses and describes virus-host interactions in GSL sediments along a salinity gradient. The results demonstrate that salinity along with the concentration of organic carbon and inorganic nutrients governs the viral, bacterial, and archaeal diversity in this habitat. Identification of auxiliary metabolic genes for photosynthesis, carbon fixation, formaldehyde assimilation, and nitric oxide reduction sheds light on the roles played by GSL viruses in global biogeochemical cycles.
