Antimicrobial Study of Amla, Turmeric, Ginger, Garlic, and Aloe Vera on E. coli and Comparative Analysis with Common Antibiotics (Penicillin, Streptomycin, Amoxicillin, Ciprofloxacin, and Tetracycline). Escherichia coli

Conducted a certified study in Microbiology to assess the antimicrobial properties of natural substances compared to common antibiotics.The study was to investigate the antimicrobial properties of five commonly used medicinalplants - Amla, Turmeric, Ginger, Garlic, and Aloe Vera - against Escherichia coli (E. coli)bacteria, and compare their efficacy with that of five widely prescribed antibiotics - penicillin,streptomycin, amoxicillin, ciprofloxacin, and tetracycline. The results showed that amla,turmeric, ginger, garlic, and aloe vera exhibited the highest zones of inhibition, with Gingershowing the highest zone of inhibition. The comparative analysis revealed that Ginger extractpossessed the highest antibacterial activity among the tested plant extracts, surpassing theefficacies of streptomycin. Garlic extract also demonstrated the highest levels of inhibitioncompared to that of amoxicillin. Overall, our findings suggest that ginger and garlic have thepotential as natural antibacterial agents, and they could be used as alternative or adjunctivetreatments to conventional antibiotics in combating bacterial infections.The objective of this study is to scientifically validate the antimicrobial efficacy of these plantsagainst Escherichia coli, a common and problematic pathogen. Through rigorous experimentalmethodologies and comparative analysis with conventional antibiotics, this research aims toidentify viable natural alternatives that could complement or replace existing antibiotictreatments, thereby mitigating the development of antibiotic resistance.This work has been conducted at the Swami Vivekananda Institute of Modern Science underthe expert guidance of Professor Dr. Debasree Sinha. The contributions and support of faculty,peers, and family have been invaluable in successfully completing this project. Thecollaborative spirit and unwavering dedication of all involved have been instrumental inadvancing this research.We hope that the findings of this thesis will contribute meaningfully to the fields ofmicrobiology and pharmacology, offering new insights into the integration of traditionalmedicinal knowledge with modern scientific practices. This research underscores theimportance of exploring diverse sources of antimicrobial agents and aims to inspire furtherstudies in the pursuit of sustainable and effective health solutions
