Although both biodegradable plastics and lignite are rich in organic matters, using them as an efficient source of generating clean energy still poses problems. Accordingly, polylactic acid (PLA), poly (butyleneadipate-co-terephthalate) (PBAT), polyhydroxyalkanoates (PHA) raw materials were adopted the fermentation substrates. Domesticated biogas slurry was also applied bacteria source. Gompertz cumulative gas production equation simulations, GC-MS, 3D-EEM metagenomic analyses employed to evaluate changes anaerobic co-digestion matter conversion metabolic pathways. The results showed that BPs rapidly adapted system consequently, increased biomethane. synergistic degradation found produce more small molecule acids, alcohols, alkanes. This is while, strong fluorescence intensities exhibited by spectra. Co-digestion significantly gene abundance some pathways, enzymes related CO2, methanol methylamine, dimethylamine trimethylamine methane pathways pathway. As result, efficiency improved. Hence, it can be argued findings study provide a new method for utilization lignite.

Abstract Extracellular polymeric substances (EPS) are a vital component of microbial residues which contribute to soil organic carbon (SOC). However, despite various conjectures and hypotheses regarding EPS controls, empirical research experimental evidence validate these theories have remained highly limited. In this study, we addressed knowledge gap by conducting extensive sampling across Europe, encompassing diverse climates bedrock land use types, systematically investigate contents large-scale controls. We found that significantly influenced the concentration, contribution EPS-carbon (C) SOC, as well production efficiency. The average concentration was 956 ± 55 µg g⁻¹ (n = 92 sites), with EPS-C contributing on 1.6 0.1% SOC. Soil concentrations were higher carbonate than silicate sedimentary geologies. terms use, grassland soils had compared cropland but did not differ from woodland soils.

On large scale, accumulation promoted its factors promoting sorption stabilization EPS, such clay exchangeable Ca Fe oxides. These findings underscore significant yet overlooked role critical soil-stable pool, it influences SOC should be further studied better understand cycling.

Roots can add significant amounts of carbon (C) to the subsoil, which improves soil physical properties and mitigate climate change. About 5% croplands in Germany have been deep-ploughed (30–120 cm) at least once. This provide better root access subsoil may increase yields, but little is known on fate root-derived C (at depth greater than 30 after deep-ploughing.

Abstract Microbial necromass carbon (MNC) is a major contributor to soil organic (SOC) sequestration. Fertilization combined with plastic film mulching, as an intensive agricultural practice increase crop yields, affects microbial growth and metabolism. Nevertheless, how fertilization mulching SOC sequestration by mediating MNC dynamics remains elusive. Here, the no‐mulching sub‐treatments were set under three treatments (no fertilization, NF; inorganic IF; manure, MF), 900‐day field incubation experiment using polyvinyl chloride containers was conducted in buffer zone of NF treatment. We investigated effects on composition (including fungal carbon, FNC; bacterial BNC) qualified their contributions The MF treatment with/without significantly increased contents MNC, FNC, BNC, 97%–122%, 81%–94%, 152%–210%, 60%–70% compared without over 900 days, respectively. content had strongly positive correlation particulate biomass C ( p < 0.01). During stage, proportion higher IF (37%–42%) (40%–44%) than that (31%–35%). On day 900, decreased 8.7% 7.8%, 5.1% 5.8% treatments, In contrast, did not affect contents, but FNC 4.8% 900.
