Effects of Moringa oleifera Leaf Extracts on Xanthomonas campestris pv. campestris

Xanthomonas campestris pv. campestris (Xcc) is a Gram-negative bacterium belonging to the Xanthomonodaceae family, causing black rot in crucifers. To control this pathogen, the study investigated the effect of different leaves extracts of Moringa oleife...

To control this pathogen, the study investigated the effect of different leaves extracts of <i>Moringa oleifera</i> Lam., a tropical plant, well known for its food properties and with countless applications in many different fields, from nutraceutical (hypoglycemic) to the cosmetic (sunscreen) properties. Nevertheless, several studies pointed to its antibacterial action against both Gram-negative and Gram-positive bacteria. Many bioactive compounds, including flavonoids, phenolic acids, alkaloids, isothiocyanates, tannins and saponins, contained in these extracts, are responsible for its countless activities. The analyses carried out in this study show that the methanolic, hydroalcoholic and hydroalcoholic maltodextrin extracts have both bacteriostatic and bactericidal effects at concentrations of 0.5, 0.5 and 0.1 mg/mL respectively. In particular, the study shows how all extracts can alter membrane permeability, to adversely affect swarming motility, and to alter biofilm formation in Xcc. The in planta experiments showed a reduction of the necrosis area in the infected radishes, although the ability of the extracts to be absorbed by root systems is yet to be understood, in order to reach the target point.Riccardo FontanaAnna CaproniRaissa BuzziMariaconcetta SicurellaMattia BurattoFrancesca SalvatoriMariangela PappadàStefano ManfrediniAnna BaldisserottoPeggy MarconiMDPI AGarticle<i>Xanthomonas campestris</i><i>Moringa oleifera</i> Lamantimicrobial activitynutraceuticalcosmeceuticalBiology (General)QH301-705.5ENMicroorganisms, Vol 9, Iss 2244, p 2244 (2021)
