This study innovatively introduced two deep eutectic solvents (DES), ChCl/oxalic acid (CO) and ChCl/ethylene glycol (CE), into a 34-day co-composting process of distillery sludge (DS) distiller's grains waste (DGW) to address ammonia emissions challenges. The addition DES increased dissolved organic carbon by 67.60% 91.63%, offering more utilizable for microorganisms. SYTO9/PI staining enzyme activity tests showed CE had higher bacterial metabolic levels during the thermophilic phase than control (CK). Bacterial community analysis revealed that early dominance Lactobacillus Lysinibacillus in accelerated onset phase, reduced pile pH, significantly decreased urease production reducing Ureibacillus. Consequently, treatment led substantial drop 73.43% nitrogen loss 53.84%, compared CK.

Regulating the C/N ratio in composting is a widely accepted approach to accelerate humification process during composting. However, currently, most traditional study focus only on total ratio, and few research concern effect of carbon or nitrogen components at different bioavailable level key substances these humification. This aims clarify mechanism spent mushroom substrate (SMS). Two typically sources, cattle manure (CM) Hainan chicken (CH), were added into SMS with CM:CH 1:0, 3:1, 1:1, 1:3, 0:1, respectively. The physicochemical properties, fluorescent components, humic substance, humus precursors determined evaluate process. molecular evolution elucidated by excitation–emission matrix parallel factor Fourier transform infrared spectrum two-dimensional correlation. relationship between intermediate precursor, was clarified. results indicated that regulating material bioavailability adding compound N-rich sources an effective strategy C1H3 treatment (CM:CH 1:3) CH obtained relatively greater properties highest growth rate acid (HA), which 31.96% 27.02%, rapid reaction polysaccharide, ketone, quinone, amide DOM (LCP1) might be for fast CH. polyphenol, reducing sugar amino originated from labile-carbon-proportion I recalcitrant-carbon-proportion (RCP), II (LCP2) RCP, labile-nitrogen-proportion (LNP1), respectively, related HA. result this provides insight perspective bioavailability, may contribute disposing residue.

Regulating nitrogen source composition is efficient approach to accelerate the spent mushroom substrate (SMS) composting process. However, currently, most traditional study only focuses on total C/N ratio of initial material. Few research concerns effect carbon or components at different degradable level and their corresponding decomposed-substances humification This deciphers compare mechanism mixed manure-N sources SMS from bioavailability molecular perspective. Two biodegradable sources, cattle manure (CM) Hainan chicken (CH), were added into with CM:CH 1:0, 3:1, 1:1, 1:3, 0:1, respectively. The physicochemical properties humic substances determined evaluate compost quality. Coupling analysis spectroscopy, fluorescence, intermediate precursors conducted characterizing formation process acid. results indicated that regulating carbon-nitrogen nutrient biodegradability material by adding an effective strategy C1H3 (CM:CH 1:3) CH treatments obtained great highest growth rate acid (31.96% 27.02%, respectively). rapid reaction polysaccharide, ketone, quinone, amide in DOM (LCP1) might be key for fast CH. polyphenol, reducing sugar amino originated labile-carbon-proportion I recalcitrant-carbon-proportion (RCP), II (LCP2) RCP, labile-nitrogen-proportion (LNP1), respectively, main driving HA. result this provides a accelerating elucidates perspective C-N evolution, which may help enhance disposing efficiency residue practical field.

High-throughput sequencing and a 16S rRNA gene clone library amplicon analysis were used to study the endophytic microbial diversity in citrus leaves response Xanthomonas citri pv. Citri (Xcc) infection an effort develop biocontrol scheme for canker disease. There are more species of moderate disease (MCD) than severe (SCD) terms both Shannon Simpson index measurements. Taxonomy has shown that MCD Firmicutes group (25.2%) outnumber SCD (0.55%). Some can suppress Xcc, but leaves, they competitive position do not have dominating niche; therefore, their population is greatly decreased. Sphingomonas Methylobacterium, two genera phylum Proteobacteria, growth-promoting stress-resistant most plants comprise approximately 60% group, whereas was less abundant. In conclusion, restructures bacterial communities infected causing community evolve toward “weakening its spear strengthening shield.” This research provides support idea introducing helpful strains advance may alter relative abundance bacteria given area hence decrease likelihood by harmful bacteria. The future technology lies on functions, elucidation plant processes pathogen occurrence, development biological control technologies.
