Antibacterial activity of the seeds, roots and shoots of Lotus populations

Abstract

In this study the antibacterial activity of the ethanol, ethyl acetate and chloroform extracts from the seeds, roots and shoots of Lotus aegaeus, Lotus angustissimus, Lotus corniculatus, Lotus gebelia, Lotus palustris populations grown naturally in Turkey were investigated by using the disc diffusion and agar dilution method, against main plant pathogenic bacteria (Clavibacter michiganensis, Agrobacterium tumefaciens, Erwinia caratovora, Pseudomonas phaseolicola). According to results, the shoot ethyl acetate extract of L. aegaeus and shoot extracts of L. corniculatus against C. michiganensis and shoot extracts of all solvents of L. angustissimus against P. phaseolicola showed high antibacterial activity. This is the first report of antibacterial activity of the Lotus species against plant pathogens. In the study these stated effective extracts showed higher antibacterial effects by comparison with used chemical preservatives against sensitive bacteria. This study offers that active compounds present in Lotus species could play a big role in naturally plant preservation against plant diseases.

Phytochemistry and Antiviral Properties of Two Lotus Species ‎Growing in Egypt

“…However, Salman et al showed that the ethanolic extract of L. corniculatus had remarkable activity against some gram-negative bacterial strains, and it also showed improved susceptibility against two fungal strains (15). Demirkol reported high antibacterial activity from the chloroform, ethanol, and ethyl acetate shoot extracts of L. aegaeus and L. corniculatus against Clavibacter michiganensis and the shoot extracts of all solvents of L. angustissimus against Pseudomonas phaseolicola (24). It was reported that 5-methyloctadecane, hexadecanoic acid methyl ester (palmitic acid, methyl ester), dodecanoic acid,2,3-bis(acetyloxy)propyl ester, and dodecane found in methanolic extract of Colpomenia sinuosa, Padina pavonia, Cystoseira barbata, and Sargassum vulgare showed potential antifungal activities against Aspergillus niger, A. flavus, Penicillium parasiticus, Candida utilis, and Fusarium solani (27).…”

Evaluation of physicochemical properties and shelf life of regular‐fat model sausages by wrapping with sodium alginate active film containing different levels and drying method of lotus rhizome root powder

“…Results of texture profile analysis (TPA) of RFMSs wrapped with various films are shown in counts of RFMSs because SAFs increase the water barrier and prevent microbial contamination (Song et al, 2011). Furthermore, extracts of lotus rhizome root had high antibacterial effects against sensitive bacteria (Demirkol, 2018). In addition, oven-dried LRRP had better antimicrobial activities than freeze-dried LRRP.…”

Efficacy of Bacterial Isolates against Causal Agent of Late Blight of Potato, Phytophthora infestans

“…Pseudomonas strains (RB15, RB30) and B. cereus (RB13) were reported cyanogen as well as siderophore producers along with having antagonistic activity against fungal phytopathogens (Rani et al, 2016). Shoot extract of Lotus aegaeus and L. corniculatus and shoot extracts of all solvents of L. angustissimus showed potential antibacterial activity against Clavibacter michiganensis and Pseudomonas phaseolicola respectively (Demirkol, 2018). According to Padmaja et al (2011), lactic acid bacteria like Lactobacillus, Leuconostoc, Pediococcus and Lactococcus showed potential antimicrobial activity.…”
