Application of Cold Atmospheric Pressure Plasma Jet Results in Achievement of Universal Antibacterial Properties on Various Plant Seeds

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(3), P. 1255 - 1255

Published: Jan. 26, 2025

In view of a constant growth in the human population on Earth, provision necessary amount high-quality food looks challenging. As over 10% crop yields are annually lost due to presence phytopathogens, development novel, eco-friendly methods pest eradication might contribute avoiding nutritional shortages. Here, we propose controlled application cold atmospheric pressure plasma (CAPP) generated form an jet (APPJ), for which conducted multivariate optimization working parameters with use design experiments (DoE) addition response surface methodology (RSM). After estimating optimal operating conditions APPJ, determined inactivation rates caused by 2 min CAPP exposure towards bacterial phytopathogens from three species Dickeya solani, Pectobacterium atrosepticum and carotovorum artificially inoculated plant seeds four species. Logarithmic reductions, as key result this work, were enclosed range 1.61–4.95 case Cucumis sativus, Pisum sativum, Vigna radiata, while bacteria-inoculated Zea mays seeds, lower antibacterial properties APPJ equaling 0.86–1.12 logs noted. The herein applied did not reveal any statistically significant detrimental effects germination seed coat integrity, or early growth. Even promotion 20.96% was observed APPJ-exposed seeds. By applying colorimetric assays optical emission spectrometry (OES), oxidative potential identifying reactive oxygen (ROS) •OH, •HO2, •O2−, O3, 1O2 nitrogen (RNS) N, NO2, NO3 responsible APPJ. summary, universal antiphytopathogenic treatment reached proper revealed against strains family Pectobacteriaceae diverse data presented may future agriculture field provide alternatives pesticides prevention-based control pathogenic bacteria.

Antibacterial potential of extracts and metabolites isolated from the endophytic fungus Chaetomium cochliodes against phytopathogenic bacteria

Hellenic Plant Protection Journal, Journal Year: 2024, Volume and Issue: 17(2), P. 85 - 96

Published: July 1, 2024

Summary Five fungal endophytes, Alternaria sp., Aspergillus Chaetomium Rhizopus sp. and Curvularia were isolated from an Egyptian herbaceous plant, Tribulus terrestris , tested for their antibacterial activity against three phytopathogenic bacteria ( Pectobacterium carotovorum subsp. carotovorum, Ralstonia solanacearum, Pseudomonas syringae pv. ). showed the highest activity. This strain was identified morphologically molecularly as cochliodes MS03 (MW898133) based on ITS1-5.8S rRNA-ITS2 genomic region. caused 15 8 mm inhibition zones of P. R. solanacearum respectively. isolate fermented extracted with ethyl acetate. The crude extract C. strong (inhibition zone = 27 mm). Bioassay guided isolation using silica gel column chromatography conducted to bioactive secondary metabolites. Minimum inhibitory concentrations (MICs) 500, 32 4 mg/L extract, fraction 14 15, respectively, . Bioactive fractions analyzed by GC/MS. pure compound 9,12-octadecadienoic acid (Z,Z) chemical structure confirmed H 1 NMR C 13 spectral analysis. a promising MIC value mg/L.
