Changes in the Glucose Concentration Affect the Formation of Humic-like Substances in Polyphenol–Maillard Reactions Involving Gibbsite

Molecules, Год журнала: 2024, Номер 29(9), С. 2115 - 2115

Опубликована: Май 3, 2024

The polyphenol–Maillard reaction is considered one of the important pathways in formation humic-like substances (HLSs). Glucose serves as a microbial energy source that drives humification process. However, effects changes glucose, particularly its concentration, on abiotic remain unclear. Given requires high precursor concentrations and elevated temperatures (which are not present soil), gibbsite was used catalyst to overcome energetic barriers. Catechol glycine were introduced fixed into phosphate-buffered solution containing using liquid shake-flask incubation method, while concentration glucose controlled sterile system. supernatant fluid HLS components dynamically extracted over period 360 h for analysis, thus revealing influence different pathways. results showed following: (1) addition led higher degree aromatic condensation fluid. In contrast, without (Glu0) control group any Maillard (CK group) exhibited lower degrees condensation. Although total organic C (TOC) content decreased all treatments during period, precursors effectively mitigated decreasing trend TOC content. (2) While acid (CHLA) CHLA/CFLA ratio (the fulvic-like acid) varying increases after incubation, resulted more noticeable increase CHLA compared CK group. This indicated FLA converted HLA, which humification, improving quality HLS. catechol or with 0.06 mol/L beneficial enhancing HLA humification.

Effect of Artificial Humic Acids Derived from Municipal Sludge on Plant Growth, Soil Fertility, and Dissolved Organic Matter

Agriculture, Год журнала: 2024, Номер 14(11), С. 1946 - 1946

Due to its high nutrient utilization efficiency, liquid organic fertilizer has become a research hotspot in the field of agricultural planting. Artificial humic acids, which are near-nature products, can be deemed as green fertilizer, but few studies have been reported, limited their further application. In this study, artificial acids were derived from municipal sludge, and effect on rice growth, soil fertility, dissolved matter was investigated using multi-chamber root box experiments. The shoot biomass significantly enhanced by heavy metal concentration within safe limits. limit decrease pH, especially far-rhizosphere zone, improve distribution nutrients rhizosphere, near-rhizosphere, zones. use led significant electrical conductivity. carbon content zone increased, fluorescence intensity rhizosphere increased. proportion specific components just slightly changed near-rhizosphere promoted humification findings indicate that environmental impact is different conventional chemical fertilizers, they show huge potential agriculture field.
