Thesis Abstract

Abstract
The increasing resistance of pathogenic bacteria to conventional antibiotics poses a significant challenge to public health. In light of this, the exploration of alternative antimicrobial agents, such as natural plant extracts, has gained attention in recent years. This thesis focuses on the investigation of the antimicrobial properties of natural plant extracts against pathogenic bacteria. The study aims to evaluate the effectiveness of these plant extracts in inhibiting the growth of various pathogenic bacteria and to identify the potential mechanisms underlying their antimicrobial activity. Chapter One provides an introduction to the research topic, discussing the background of the study, the problem statement, objectives of the study, limitations, scope, significance, structure of the thesis, and definitions of key terms. Chapter Two presents a comprehensive literature review, analyzing existing research on the antimicrobial properties of natural plant extracts and their potential applications in combating pathogenic bacteria. The chapter highlights the importance of exploring natural alternatives to traditional antibiotics and provides a theoretical framework for the study. Chapter Three outlines the research methodology employed in this study, including the selection and preparation of natural plant extracts, bacterial strains used for testing, experimental procedures, and data analysis methods. The chapter also discusses the ethical considerations and limitations of the research methodology. Chapter Four presents a detailed discussion of the findings obtained from the experimental evaluation of the antimicrobial properties of natural plant extracts against pathogenic bacteria. The chapter analyzes the effectiveness of different plant extracts in inhibiting bacterial growth, identifies the most potent extracts, and explores potential mechanisms of action. The discussion also highlights any challenges encountered during the experimental process and offers insights for future research directions. Chapter Five offers a conclusion and summary of the project thesis, summarizing the key findings, implications, and contributions to the field of microbiology. The chapter also discusses the practical applications of the research findings, potential limitations, and recommendations for further studies. Overall, this thesis contributes to the growing body of knowledge on alternative antimicrobial agents and provides valuable insights into the potential use of natural plant extracts in combating pathogenic bacteria.
