THE ACTIVITY OF ESSENTIAL OILS OBTAINED FROM SPECIES AND INTERSPECIES HYBRIDS OF THE Mentha GENUS AGAINST SELECTED PLANT PATHOGENIC BACTERIA

Abstract

Plant essential oils of six aromatic herb species and interspecies hybrids of the family Lamiaceae – chocolate mint (Mentha piperita × ‘Chocolate’), pineapple mint (Mentha suaveolens ‘Variegata’), apple mint (Mentha × rotundifolia), spearmint (Mentha spicata), orange mint (Mentha × piperita ‘Granada’) and strawberry mint (Mentha × villosa ‘Strawberry’) – were investigated for antimicrobial effects against plant pathogenic bacteria: Agrobacterium tumefaciens, Pseudomonas syringae pv. syringae and Xanthomonas arboricola pv. corylina. The screening was carried out in vitro on agar plates filled with the target organism. All essential oils screened exhibited a higher level of antibacterial activity against A. tumefaciens and X. arboricola pv. corylina than streptomycin used as a standard in all tests. The antimicrobial effect of streptomycin and five mint oils was at the same level for P. syringae pv. syringae. There were no significant differences in the influence of the chocolate mint oil on the growth inhibition of all bacteria tested. Plant essential oils from pineapple mint, apple mint, spearmint and strawberry mint showed the weakest antimicrobial activity against P. syringae pv. syringae and the strongest towards A. tumefaciens and X. arboricola pv. corylina. The essential oils from strawberry mint, pineapple mint, spearmint and apple mint had the strongest effect on A. tumefaciens, and the lowest inhibitory activity was exhibited by the chocolate mint and orange mint essential oils. X. arboricola pv. corylina was the most sensitive to the strawberry mint, pineapple mint and spearmint oils. The chocolate mint oil showed the greatest activity against P. syringae pv. syringae.

“…Although, very few studies were conducted to assess efficacy of essential oils from the medicinal plants, including those used in this study (such as M. spicata, T. spicata var. spicata and T. serpyllum) against crown gall disease agent R. radiobacter (Basim et al, 2000;Ateeq-ur-Rehman et al, 2009;Schollenberger et al, 2018), to the best of our knowledge there is no research on the evaluation of the efficacy of essential oils used in the present study against gall forming bacterial species such as P. savastanoi pv. savastanoi and P. savastanoi pv.…”

“…Earlier studies have demonstrated the antibacterial activities of essential oils obtained from different plant species to retard and inhibit not only the growth of gal forming bacterial disease agent R. radiobacter (Basim et al, 2000;Iacobellis et al, 2005;Ateeq-ur-Rehman et al, 2009;Mohan et al, 2011;Melkani et al, 2011;Moghaddam et al, 2014;Badawy and Abdelgaleil, 2014;Schollenberger et al, 2018;Turker et al, 2018;Ben Hsouna et al, 2019) but also other plant pathogenic bacterial disease agents such as Pseudomonas syringae pv. syringae (Schollenberger et al, 2018;Moghaddam et al, 2014), Xanthomonas arboricola pv. corylina (Schollenberger et al, 2018), Ralstonia solanacearum (Moghaddam et al, 2014), Pseudomonas syringae pv.…”

“…Observations in the eastern Mediterranean region of Hatay province, Turkey indicate that there exist veld types with a rich composition of indigenous aromatic and medicinal plant species belonging Lamiaceae, Lauraceae and Apiaceae families. Although, very few studies were conducted to assess efficacy of essential oils from the medicinal plants, including those used in this study against crown gall disease agent R. radiobacter (Basim et al, 2000;Ateeq-ur-Rehman et al, 2009;Schollenberger et al, 2018), to the best of our knowledge there is no research has been conducted on antibacterial activities of essential oils from aromatic plants used in this study against the gall forming bacterial species causing bacterial knot, gall and tumor by P. savastanoi pv. savastanoi and P. savastanoi pv.…”

The Antibacterial Effect of Selected Essential Oils and Their Bioactive Constituents on Pseudomonas savastanoi pv. savastanoi: Phytotoxic Properties and Potential for Future Olive Disease Control

“…Specifically, terpenoids have been recognized as interesting molecules for their antimicrobial activity, making EOs suitable candidates for bacterial control [7,8]. However, the composition of EOs varies depending on the growth conditions of plants, including the climate, plant genetics, cultivation practices, and physiological condition of plants [9]. The EOs derived from plants belonging to the Lamiaceae family, e.g., genera Mentha, Melissa, Salvia, Thymus, and Origanum, showed effective control of numerous economically important phytopathogenic bacteria [9][10][11][12][13][14][15][16][17][18][19][20].…”
