The Effectiveness of Lemongrass Extract on the Growth of Porphyromonas Gingival ATCC® 33277 ™ (in-vitro) Bacteria

Introduction

Periodontitis, a condition characterized by inflammation of the gum tissue and alveolar bone resorption, is a major concern in oral health. Porphyromonas gingivalis, a bacterium responsible for this condition, has become increasingly resistant to modern antibiotics. In search of alternative treatments, researchers have turned to natural extracts, such as lemongrass, which have been shown to possess significant antibacterial effects. This study aims to investigate the effectiveness of lemongrass extract on the growth of Porphyromonas gingivalis ATCC® 33277 ™ bacteria, with a focus on its Minimum Inhibition Level (KHM) and Minimum Killing Level (KBM) at various extract concentrations.

The Importance of Lemongrass Extract

Lemongrass extract is known to contain active compounds such as citral and geranial, which have been shown to exhibit significant antibacterial effects. Citral, in particular, has been found to damage the fatty membrane layer of bacterial cells, including Porphyromonas gingivalis. This bacterium is a major cause of periodontitis, and its growth must be inhibited or killed to prevent the progression of this condition. The use of lemongrass extract as an antibacterial agent offers a promising alternative to modern antibiotics, which are becoming increasingly ineffective against bacterial infections.

Research Methods

This study employed an experimental laboratory method with a Posttest Control Group design. Porphyromonas gingivalis ATCC® 33277 ™ bacteria were obtained from the USU Hospital Microbiology Laboratory. To test the effectiveness of lemongrass extract, dilution tests were conducted on Mueller Hinton Broth (MHB) media, followed by subculture on agar nutrient media. The study was repeated five times to ensure the accuracy of the results.

Research Results

The results of the descriptive analysis conducted through the ANOVA test showed that a 25% concentration of lemongrass extract functioned as the Minimum Inhibition Level (KHM), while a 50% concentration functioned as the Minimum Killing Level (KBM). This indicates that lemongrass extract not only inhibits the growth of bacteria at lower concentrations but is also able to kill bacteria at higher concentrations.

Discussion

The effectiveness of lemongrass extract as an antibacterial agent lies in its chemical components, which work well against Porphyromonas gingivalis. The use of a 25% concentration shows a high potential for use in the treatment of periodontitis, where inhibition of bacterial growth is an important first step. Meanwhile, a 50% concentration not only inhibits but also kills bacteria, providing a more comprehensive solution. The increase in bacterial resistance to modern antibiotics highlights the need for alternative treatments, and the use of natural extracts such as lemongrass can be a promising solution.

Conclusion

This study proves that lemongrass extract can be an effective antibacterial agent against Porphyromonas Gingival ATCC® 33277 ™ bacteria. With a concentration of 25% able to inhibit the growth of bacteria, and a concentration of 50% able to kill bacteria, this study makes a significant contribution to the search for alternative natural-based treatments that are safer and effective in dealing with oral health problems related to periodontitis.

Future Directions

This study opens the way for further research on lemongrass extract in treating other bacterial infections. The use of natural extracts as antibacterial agents offers a promising alternative to modern antibiotics, and further studies are needed to explore the potential of lemongrass extract in this context. Additionally, the development of lemongrass-based products for oral health care could provide a safer and more effective solution for preventing and treating periodontitis.

Limitations

This study has several limitations that should be addressed in future research. Firstly, the study was conducted in vitro, and further studies are needed to investigate the effectiveness of lemongrass extract in vivo. Secondly, the study only investigated the effectiveness of lemongrass extract against Porphyromonas gingivalis, and further studies are needed to explore its effectiveness against other bacterial species. Finally, the study only investigated the use of lemongrass extract as a standalone treatment, and further studies are needed to investigate its use in combination with other treatments.

Recommendations

Based on the findings of this study, the following recommendations are made:

Further research is needed to investigate the effectiveness of lemongrass extract in vivo.
Further studies are needed to explore the effectiveness of lemongrass extract against other bacterial species.
The development of lemongrass-based products for oral health care could provide a safer and more effective solution for preventing and treating periodontitis.
The use of lemongrass extract as a standalone treatment or in combination with other treatments should be explored in future studies.

Conclusion

In conclusion, this study proves that lemongrass extract can be an effective antibacterial agent against Porphyromonas Gingival ATCC® 33277 ™ bacteria. With a concentration of 25% able to inhibit the growth of bacteria, and a concentration of 50% able to kill bacteria, this study makes a significant contribution to the search for alternative natural-based treatments that are safer and effective in dealing with oral health problems related to periodontitis. Further research is needed to explore the potential of lemongrass extract in treating other bacterial infections and to develop lemongrass-based products for oral health care.
