Application of Biosynthesized Silver Nanoparticles from Oak Fruit Exudates against Pectobacterium carotovorum subsp. carotovorum Causing Postharvest Soft Rot Disease in Vegetables

Abstract

The main goal of our study was to determine whether biosynthesized silver nanoparticles (SNPs) could be used as a novel antibacterial material in order to control soft rot in vegetables. Exudates from oak fruit were used in the green synthesis of SNPs. Postharvest soft rot disease in vegetables has resulted in significant crop losses all over the globe. Because managing Pectobacterium carotovorum subsp. carotovorum (Pcc), the causal agent of soft rot disease, is difficult due to its wide host range, developing innovative disease-management methods that do not involve the use of hazardous chemicals is a top priority for maintaining sustainable agriculture. The current research has found that silver nanoparticles (SNPs) have a detrimental effect on the progression of Pcc and soft rot disease in in vitro conditions. At SNPs’ sub-MIC, the greatest levels of inhibition against tissue maceration were 22, 19.8, 21.5, and 18.5 percent in potato, zucchini, carrot, and eggplant, respectively. SNP treatment of tubers and fruits had a noteworthy suppressive impact on soft rot disease symptoms as compared to controls. SNPs may be able to replace chemical pesticides in the management and prevention of soft rot disease in vegetables in postharvest settings, according to this study.

Green synthesis of silver nanoparticles by sweet cherry and its application against cherry spot disease

“…Given the numerous reports on the antimicrobial activity of SNPs, this investigation sought to contribute to the existing knowledge in this field. Green-synthesized SNPs exhibited a prominent absorption band at 440 nm, which can be attributed to their surface plasmon resonance (SRP) characteristics [ 36 ].…”

New Advances in Nano-Enabled Weed Management Using Poly(Epsilon-Caprolactone)-Based Nanoherbicides: A Review

“…Almost all metal elements, including transitional elements and lanthanide metals, are included in the range of metal centers that is employed. Copper, iron, and zinc are often and extensively used [59,60]. Likewise, mesoporous silica nanoparticles (MSNs) have strong adsorption performance because of their large areas of contact, tunable pores, and modified interfaces, as well as being biocompatible and environmentally friendly.…”

Identification of the chemical profile and evaluation of the antimicrobial effect of Eryngium billardieri Delar essential oil component against bacterial species of agricultural and food interest

“…It is quite obvious that phytopathogens along with foodborne bacteria significantly contribute to the overall loss in crop yields worldwide (Mansfield et al, 2012 ; Hameed et al, 2018 ). Sustainable food production through biological methods is an inexpensive substitute for conventional physical and non-biodegradable chemical methods (Allafchian et al, 2022 ; Soltani Nejad et al, 2023 ), which aims to hinder the development of a multiple resistance crisis among pathogenic microorganisms in relation to these substances (Karimi et al, 2019 ), preventing their extended environmental pollution and reduced effectiveness (Giaouris et al, 2014 ).…”
