This study evaluates the potential of hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) as an oxidant for the simultaneous removal of multiple VA groups during the aerobic swine liquid manure-based fertilization process. For this purpose, swine manure spiked with 10 mg L<sup>−1</sup> of target VAs was treated with 1.0% (v v<sup>−1</sup>) H<sub>2</sub>O<sub>2</sub> and then continuously aerated for 28 days in a laboratory-scale aerobic liquid fertilization reactor. The results indicate that 1.0% H<sub>2</sub>O<sub>2</sub> effectively degrades penicillins, achieving removal rates exceeding 90% within 24 h. Tetracyclines and macrolides exhibited moderate susceptibility to H<sub>2</sub>O<sub>2</sub> oxidation, after 28 days, achieving average removal rates exceeding 90% and 95%, respectively. In contrast, the sulfonamide group displayed the lowest removal efficiency, with an average removal rate of 70%. The study further reveals that the oxidative effect of H<sub>2</sub>O<sub>2</sub> is the most pronounced in the early stages of fertilization, with degradation rates plateauing over time due to the gradual decomposition of H<sub>2</sub>O<sub>2</sub> and interactions with organic matter in swine manure. Despite these limitations, H<sub>2</sub>O<sub>2</sub> treatment did not significantly change the key chemical properties of the final liquid fertilizer, maintaining its fertilizer efficacy. These findings suggest that H<sub>2</sub>O<sub>2</sub>-based oxidation could be a cost-effective and an eco-friendly substitute for traditional methods for mitigating VA contamination in liquid manure fertilization systems. The results will help to better understand the effect of H<sub>2</sub>O<sub>2</sub> on the reduction of VAs during the liquid fertilization process, which has the potential to make a significant contribution to mitigating threats to public health and the ecosystems associated with the application of liquid fertilizer in agricultural environments.</p></div>","PeriodicalId":467,"journal":{"name":"Applied Biological Chemistry","volume":"68 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://applbiolchem.springeropen.com/counter/pdf/10.1186/s13765-025-01033-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145037034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rice cultivars were exposed to different levels of salt stress (0–300 mM NaCl) after seedling establishment under natural sunshine. Salinity posed a significant growth decline in both the rice cultivars. Under increasing salinity stress, BRRI dhan43 exhibited a pronounced reduction in overall growth. Chlorophyll and proline content declined significantly in BRRI dhan43 with rising salt concentration. A marked decrease in antioxidant enzyme activities, including superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) was also observed. Furthermore, salinity severely reduced grain yield and associated yield parameters in BRRI dhan43. In contrast, BRRI dhan55 demonstrated comparatively better tolerance under salinity. Although chlorophyll content was reduced in BRRI dhan55, the decrease was less pronounced than in BRRI dhan43, while proline content increased with increasing salinity. Additionally, antioxidant enzyme activities (SOD, CAT, and APX) were increased in BRRI dhan55. However, grain yield and yield attributes in BRRI dhan55 were moderately affected by salinity, showing noticeably less reduction compared to BRRI dhan43.

GC-MS analysis demonstrated a remarkable 2.7-fold increase in total flavor compounds (TFCs) of Maillard reaction samples (MRSs) than those of enzymolysis extract of hawthorn. ROAV analysis indicated 2,3-dihydro-3,5-dihydroxy-6-methyl-4<i>H</i>-pyran-4-one (DDMP), furfural, 2-methylbutyric acid, hexyl acetate, linalool, decanal, and <i>α</i>-ionone were the key flavor compounds of MRSs, which contributed to the sweetness, roasting, fruity, and acidic aromas. The antioxidant activity were obviously enhanced after Maillard reaction that could be associated with the yielded DDMP and 4-vinylphenol.</p></div>","PeriodicalId":467,"journal":{"name":"Applied Biological Chemistry","volume":"68 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://applbiolchem.springeropen.com/counter/pdf/10.1186/s13765-025-01022-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
