Microbial-driven processes, including nitrification and denitrification closely related to soil nitrous oxide (N2O) production, are orchestrated by a network of enzymes genes such as amoA from ammonia-oxidizing bacteria (AOB) archaea (AOA), narG (nitrate reductase), nirS nirK (nitrite nosZ (N2O reductase). However, how climatic factors agricultural practices could influence these processes and, consequently, N2O emissions remain unclear. In this comprehensive review, we quantitatively assessed the effects on nitrogen using mega-analysis (i.e., meta-meta-analysis). The results showed that global warming increased rates, leading an overall increase in 159.7%. Elevated CO2 stimulated both with substantial emission 40.6%. Nitrogen fertilization amplified NH4+-N NO3−-N contents, promoting AOB, nirS, nirK, caused 153.2% emission. application biochar enhanced AOA, nosZ, ultimately reducing 15.8%. Exposure microplastics mostly process 140.4%. These findings provide valuable insights into mechanistic underpinnings microbial regulation emissions.

Regulatory Mechanisms of Exogenous Acyl-Homoserine Lactones in the Aerobic Ammonia Oxidation Process Under Stress Conditions

Microorganisms, Год журнала: 2025, Номер 13(3), С. 663 - 663

Опубликована: Март 14, 2025

This study investigated the mechanism by which N-acyl-homoserine lactone (AHL) signaling molecules influence ammonia-oxidizing microorganisms (AOMs) under inhibitory conditions. In laboratory-scale sequential batch reactors (SBRs), effects of different AHLs (C6-HSL and C8-HSL) on metabolic activity, microbial community structure, quorum sensing (QS) system response AOMs were examined. Caffeic acid, 1-octyne, allylthiourea used as ammoxidation inhibitors. The results indicated that conditions, effectively reduced loss ammonia oxidation activity enhanced resistance to unfavorable environments. Additionally, enriched in community, wherein C6-HSL significantly increased abundance amoA genes AOMs. Furthermore, maintained QS-related preserved communication ability between microorganisms. Correlation analysis revealed a positive relationship QS functional bacteria, suggesting can regulate process. Overall, exogenous improve competitive survival

Impact of Steam-Exploded Feather Incorporation on the Biodegradation Performance of Renewable Biocomposites

Polymers, Год журнала: 2025, Номер 17(7), С. 910 - 910

Опубликована: Март 28, 2025

The increasing environmental concerns regarding plastic waste, especially in agriculture, have driven the search for sustainable alternatives. Agricultural plastics, such as mulching films and greenhouse covers, are heavily reliant on petrochemical-derived materials, which persist environment contribute to long-term pollution. This study explores use of biodegradable biocomposites made from steam explosion-treated chicken feathers various polymer matrices address these issues. Chicken feathers, a waste by-product poultry industry, present an excellent biodegradability result explosion treatment contain nitrogen, potentially enhancing soil fertility. were characterized by thermal stability, mechanical properties, biodegradability, ecotoxicity assessments carried out studying incorporation into soil. Results showed that treated increased water absorption capacity composites, promoting faster disintegration biodegradation. In particular, with polyhydroxyalkanoates Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) exhibited significant increase degradation rates, 3-10% first month pure 40-50% when reinforced feathers. Meanwhile, those polylactic acid slower degradation. Furthermore, addition positively influenced crop growth at low concentrations, acting slow-release fertilizer. However, high concentrations negatively affect plant due excess nitrogen. These findings highlight potential valuable, filler agricultural bioplastics, contributing valorization environmentally friendly farming practices.

Field efficacy of urease inhibitors for mitigation of ammonia emissions in agricultural field settings: a systematic review

Globally, ammonia (NH 3 ) is one of the key air pollutants and reducing NH emissions associated indirect emission greenhouse gas nitrous oxide remains challenging for agricultural sector. During past three decades, a number urease inhibitors have been placed on market with goal loss from urea containing fertilisers. N–(n-butyl) thiophosphoric triamide (NBPT), N–(2-nitrophenyl) phosphoric (2-NPT), 3:1 ratio NBPT + N-(n-propyl) (NPPT) maleic itaconic acid co-polymer (MIP) are registered under European Commission Fertilising Products Regulation (FPR). However, availability several inhibitor options has raised questions farmers, policymakers inventory compiling authorities regarding field efficacy different available loss.

Abstract BACKGROUND Sorghum ( bicolor L. Moench) is a cereal crop known for its biological nitrification inhibition (BNI) capacity, plant‐mediated activity limiting pathway. The use of BNI‐producing plants represents an environmentally friendly and cost‐effective approach to reduce nitrogen (N) losses, such as nitrate (NO 3 − ) leaching nitrous oxide (N 2 O) gas emissions. present study aimed test the effectiveness different S. cultivars in rotation retain ammonium (NH 4 + soils promote N availability subsequent wheat crop. A two‐year field was established with four sorghum followed by winter Triticum aestivum L.). Urea alone or combined urease inhibitor ‐( n ‐butyl) thiophosphoric triamide applied NH ‐based fertilization regimes. RESULTS Adding maintained higher soil content reduced ammonia‐oxidizing bacteria population during cultivation. However, benefits on growth were cultivar‐dependent. Notably, further reduction abundance Voyenn increased Vilomene suggested BNI potential these cultivars. Importantly, precedent enhanced yield both CONCLUSION Overall, confirms that suitable catch emphasizes importance selecting proper cultivar maximize target crop, at same time minimizing losses. Furthermore, developing strategies selected application inhibitors enables enhance productivity forage, achieving added value rotation. © 2024 Author(s).
