Abstract BACKGROUND Aerobic fermentation always suffers from nitrogen loss and low humification degree. The objective of this study was to investigate the promotion phosphate buffer on organic matter degradation precursor polymerization into humus (HS) in aerobic fermentation, analyze key roles played by different precursors. In order achieve this, sludge tests were conducted control (CK), addition treatment (KP) potassium chloride (K). RESULTS HS content KP exhibited a notable increase compared CK K treatments, with maximum 38.29%. addition, improved retention capacity complexity structure. Phosphate enhanced both polyphenol Maillard pathways promoting condensation precursors (polysaccharides, reducing sugars, polyphenols, amino acids proteins). Among these precursors, proteins identified as driving phosphate. CONCLUSIONS Phosphate, an exogenous additive system, reduces while form HS, which benefits improvement soil fertility crop growth upon fertilizer application. © 2024 Society Chemical Industry (SCI).

Difficulty in degrading lignocellulose during composting leads to reduced humic substance content mineralization. Because of this, the experiment is focused on investigating effect clay addition with Fenton-like effects preprocessing substance. Setting treatment groups were CK, Z, FeZ, and mineral CK+, Z+, FeZ+. The results showed that group(FeZ)increased precursor by 31.3%. minerals increased conversion: FeZ+ > FeZ Z+ Z CK+ CK. pre-treatment resulted a significant, amount generated each group was 120.0 mg/g (CK), 141.6 (CK+), 135.8 (Z), 160.4 (Z+), 165.2 (FeZ), 180.9 (FeZ+), at same time component varies. Upon coupling treatment, microbial structure becomes progressively more complex, dominant genera change, diversity increases. Structural equations confirm pretreatment combined can affect promoting transformation. On other hand, it alter community promote production fixation. This study provides new insights theoretical support for stable increase
