Thesis Overview

The project titled "Investigating the antimicrobial properties of natural plant extracts against pathogenic bacteria" aims to explore the potential of natural plant extracts in combating pathogenic bacteria. In recent years, there has been a growing concern over the rise of antibiotic-resistant bacteria, leading to an urgent need for alternative antimicrobial agents. Natural plant extracts have long been used in traditional medicine for their antimicrobial properties, and this project seeks to scientifically investigate and validate their effectiveness. The research will focus on selecting specific natural plant extracts known for their antimicrobial properties and testing their efficacy against a range of pathogenic bacteria. Various extraction methods will be employed to obtain the active compounds from the plants, followed by thorough characterization and identification of these compounds using analytical techniques. The antimicrobial activity of the extracts will be evaluated through in vitro studies, including agar diffusion assays and determination of minimum inhibitory concentrations. Furthermore, the project will delve into the mechanisms of action underlying the antimicrobial activity of the plant extracts. Understanding how these natural compounds interact with bacterial cells can provide valuable insights into developing novel antimicrobial strategies. Additionally, potential synergistic effects between different plant extracts or with conventional antibiotics will be investigated to enhance their antimicrobial efficacy. The research methodology will involve a systematic and rigorous approach to ensure reliable and reproducible results. Statistical analysis will be employed to interpret the data obtained from the antimicrobial assays and identify significant findings. The project will also include a comprehensive literature review to contextualize the research within the existing body of knowledge on natural antimicrobial agents and their mechanisms of action. Overall, this project seeks to contribute to the growing body of research on alternative antimicrobial agents by exploring the potential of natural plant extracts. The findings from this study have the potential to inform the development of new antimicrobial therapies and address the pressing global health challenge of antibiotic resistance.
