Thesis Overview

The project titled "Investigating the antimicrobial properties of plant extracts against pathogenic bacteria" aims to explore the potential of plant extracts as alternative antimicrobial agents against pathogenic bacteria. The increasing concern over antibiotic resistance has led to a growing interest in natural compounds with antimicrobial properties, such as those found in plants. This research seeks to evaluate the effectiveness of selected plant extracts in inhibiting the growth of pathogenic bacteria through various laboratory experiments and analyses. The study will begin with a comprehensive review of existing literature on plant extracts known for their antimicrobial properties and their mechanisms of action against bacteria. This literature review will provide a theoretical foundation for the research and help identify gaps in current knowledge that this study aims to address. Following the literature review, the research methodology will be outlined, detailing the selection and preparation of plant extracts, the selection of pathogenic bacterial strains to test against, and the experimental procedures for evaluating the antimicrobial activity of the plant extracts. Various assays, such as disc diffusion assays, minimum inhibitory concentration (MIC) assays, and time-kill kinetics, will be employed to assess the effectiveness of the plant extracts in inhibiting bacterial growth. The results obtained from the experimental analysis will be thoroughly discussed in the findings chapter, highlighting the antimicrobial efficacy of different plant extracts against specific pathogenic bacteria. Factors influencing the antimicrobial activity, such as extract concentration, bacterial strain susceptibility, and potential synergistic effects, will be explored and analyzed. Based on the findings, conclusions will be drawn regarding the potential of plant extracts as antimicrobial agents against pathogenic bacteria. The significance of the study lies in its contribution to the development of alternative antimicrobial strategies that could help combat the growing threat of antibiotic resistance. The research findings could have implications for various fields, including medicine, agriculture, and food preservation. In summary, this research project aims to deepen our understanding of the antimicrobial properties of plant extracts and their potential applications in combating pathogenic bacteria. By investigating the efficacy of natural compounds as antimicrobial agents, this study seeks to contribute to the ongoing efforts to address the global challenge of antibiotic resistance.
