This study investigated the effects of different antagonistic bacterial pellets on postharvest mango preservation and the regulation of reactive oxygen species (ROS) metabolism. Methods Mangoes were sprayed separately with bacterial suspensions of four antagonistic pellets: GsBa-1, GHY-1, JQ-1, and GHY-3. Results The results showed that all four antagonistic bacterial pellets enhanced the postharvest preservation of mangoes to varying degrees, with JQ-1 exhibiting the most significant effect. On the 24th day, the mangoes in the JQ-1 treatment group showed significantly higher firmness and titratable acidity content than those in the other groups. The malondialdehyde (MDA), hydrogen peroxide (H 2 O 2 ), and superoxide anion radical (O 2 −· ) contents were reduced by 30.9, 31.2, and 46.9%, respectively, compared with those of the CK. The activities of catalase (CAT), peroxidase (POD), and glutathione peroxidase (GPx), and glutathione (GSH) content increased by 38.5, 75.2, 68.9, and 66.9%, respectively, compared with the CK. Discussion JQ-1 treatment effectively reduced the accumulation of reactive oxygen species (ROS) and delayed the decline in the activities of key antioxidant enzymes, including SOD, CAT, APX and POD. This treatment not only preserved the quality and nutritional value of mangoes but also significantly extended their storage life, providing a scientific basis and feasible approach for the development of new mango preservation technologies.","引言 采后病害造成的损失可达30%–60%，严重制约了芒果产业的可持续发展。本研究探讨了不同拮抗菌菌剂对芒果采后保鲜及活性氧（ROS）代谢调控的影响。方法 分别用4种拮抗菌剂GsBa-1、GHY-1、JQ-1和GHY-3的菌悬液喷洒芒果。结果 结果表明，4种拮抗菌剂均不同程度地提高了芒果的采后保鲜效果，其中JQ-1效果最为显著。在第24天时，JQ-1处理组芒果的硬度和可滴定酸含量显著高于其他各组。与CK相比，丙二醛（MDA）、过氧化氢（H₂O₂）和超氧阴离子自由基（O₂⁻·）含量分别降低了30.9%、31.2%和46.9%。过氧化氢酶（CAT）、过氧化物酶（POD）和谷胱甘肽过氧化物酶（GPx）活性及谷胱甘肽（GSH）含量分别较CK提高了38.5%、75.2%、68.9%和66.9%。讨论 JQ-1处理有效减少了活性氧（ROS）的积累，并延缓了包括SOD、CAT、APX和POD在内的关键抗氧化酶活性的下降。该处理不仅保持了芒果的品质和营养价值，还显著延长了其贮藏期，为开发新型芒果保鲜技术提供了科学依据和可行途径。",null,"Frontiers in Sustainable Food Systems","2026-09-17T00:00:00Z","论文",10,false,77,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":13,"relevant":21,"comment":22},16,21,17,13,1,"以拮抗细菌颗粒调控活性氧代谢延长芒果货架期，数据翔实、结论可靠，对果蔬采后减损与绿色保鲜技术有实质参考价值。",[24],{"name":10,"url":6},[26,27,28,29,30],"生物防治","芒果保鲜","采后减损","活性氧代谢","农产品贮藏",0,"10.3389\u002Ffsufs.2026.1877440",{"doi":32,"openalex_id":34,"authors":35,"venue":10,"cited_by_count":31,"oa_url":6,"card":58,"direction":62,"ingested_from":64},"W7213473131",[36,38,40,42,44,46,49,51,54,56],{"name":37,"orcid":9},"Tian Peiyi",{"name":39,"orcid":9},"Dong Ying",{"name":41,"orcid":9},"Duan Jiaying",{"name":43,"orcid":9},"Cheng Qinyang",{"name":45,"orcid":9},"Sun Jing",{"name":47,"orcid":48},"Bangdi Liu","https:\u002F\u002Forcid.org\u002F0000-0003-2302-3830",{"name":50,"orcid":9},"Zhang Min",{"name":52,"orcid":53},"Zhengrong Wang","https:\u002F\u002Forcid.org\u002F0000-0001-7471-5904",{"name":55,"orcid":9},"Maha Abdullah Alwaili",{"name":57,"orcid":9},"Nawal Al-Hoshani",{"tldr":59,"method":60,"finding":61,"direction":62,"opportunity":63},"四种拮抗细菌丸处理芒果，JQ-1通过调控活性氧代谢显著延长保鲜期。","四种拮抗细菌悬浮液喷施芒果，测定ROS代谢与抗氧化酶指标。","JQ-1处理降低MDA、H2O2和O2−·，提高CAT、POD、GPx活性及GSH，保鲜最佳。","农业绿色发展与碳","可探索拮抗细菌丸在采后保鲜中的分子机制及与其他绿色保鲜技术的协同应用。","openalex","2026-09-17T23:30:07.723677Z"]
