Bactericidal activity of Ag nanoparticles biosynthesized from Capsicum annuum pericarps against phytopathogenic Clavibacter michiganensis

Pathogenic capacity of Clavibacter michiganensis subsp. michiganensis isolated from tomato on different solanaceae: tomato (Solanum lycopersicum), potato (Solanum tuberosum), eggplant (Solanum melongena), pepper (Capsicum annuum), tobacco (Nicotiana tabacum) and petunia (Petunia hybrida)

“…In pepper plants inoculated with the Cmm bacteria, the characteristic symptoms that commonly occur in tomatoes were not observed; however, at 24 dai, a positive result was obtained in the rapid tests with immunostrips (Figure 2E) from which the strain inoculated in Mueller Hinton culture medium was reisolated (Figure 3B). At 67 dai the plants showed severe defoliation, which differs from the results reported by Yim et al (2012) where they observed in pepper plants inoculated with a Cmm strain isolated from tomato a minimal development of canker on the stems and leaf blight without wilting; however, it is worth mentioning that its evaluation period was limited to 25 days and that the presence of symptoms is associated with the susceptibility of the host cultivar, the virulence of the strain and the environmental conditions that favor or do not favor the development of the disease (Smirnov et al, 2023).…”

“…In this case, the points (xylem and phloem tissues) have a wet appearance and are deep yellow and in some cases orange. In this regard, great variability has been observed in the symptoms caused by Cmm in solanaceous plants and this depends mainly on the susceptibility of the host cultivar, the virulence of the strain and the environmental conditions that favor or do not favor the development of the disease (Smirnov et al, 2023). The bacteria moves through the vascular tissues of the fruit, reaches and enters the internal part of the seeds, these being the main source of dissemination over long distances where it is transmitted to the plant that gives rise and from there to the crop in general.…”

Phytosynthesis of silver nanoparticles with bactericidal activity against the phytopathogenic stain of Xanthomonas campestris using Capsicum annuum pericarps aqueous extract

“…Позитивним контролем слугував паперовий диск, просякнутий гентаміцином (Himedia), асептично розміщений у центрі чашки. Для розвитку бактеріальної культури Xcc чашки інкубували за 37 °С протягом 18-24 год і фіксували діаметр зони інгібування росту культури [36].…”

Antimicrobial Activities of Polyethylene Terephthalate-Waste-Derived Nanofibrous Membranes Decorated with Green Synthesized Ag Nanoparticles

“…The electrospun carrier can cause nanoparticles to distribute homogeneously and prevent their mass aggregation. In other words, the applicability of Ag nanoparticles on the electrospun polymer nanofibers can be increased [ 49 , 50 , 51 , 52 , 53 , 54 ].…”
