Antibacterial activity of plant extracts in different solvents against pathogenic bacteria: An in vitro experiment

Blog Article

Objective: To assess the antibacterial activity of 5 selected plants against 4 pathogenic bacteria.Methods: Three solvents with different polarities were used to extract antimicrobial agents from the plants via maceration technique.The agar-disc diffusion technique was adopted to primarily The Mobile Phone Affinity Scale: Enhancement and Refinement screen antibacterial activities.Broth-dilution assay was employed to determine the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC).Results: Among all extracts, the ethanol extract of Piper betle Linn showed highest antibacterial activity against Gram-positive and the negative bacteria.

MIC Instructivo para mitigar retos y desafíos de las pymes para exportar aceite de aguacate Hass con destino a Alemania and MBC of the ethanol extract of Piper betle Linn against Salmonella typhimurium were the same (1 562.50 mg/L); while it showed the highest MIC and MBC against Pseudomonas aeruginosa of 6 250 mg/L and 12 500 mg/L, respectively.Conclusions: Salmonella typhimurium is the most susceptible bacteria while Pseudomonas aeruginosa is the most resistant bacteria towards the ethanol extract of Piper betle Linn.Piper betle possesses compounds with potential antibacterial activity and might be useful as an alternative to control infectious diseases.
