# Lab Report: Antibacterial Efficacy of Strawberry, Green Apple, and Citrus Lemon Harmony Soaps via Kirby-Bauer Test
## Title
Antibacterial Efficacy of Strawberry, Green Apple, and Citrus Lemon Harmony Soaps via Kirby-Bauer Test
## Aim
To evaluate the antibacterial properties of soaps made from Alpine strawberry, Citrus lemon, and Green apple against bacterial strains using the Kirby-Bauer method.
## Objectives
1. To determine the zone of inhibition produced by each soap type against specific bacterial strains.
2. To compare the antibacterial efficacy of Alpine strawberry, Citrus lemon, and Green apple soaps.
3. To assess the statistical significance of the results through ANOVA analysis.
## Research Questions
1. Which soap exhibits the highest antibacterial activity?
2. How do the antibacterial effects of the soaps compare with positive and negative controls?
3. Is there a statistically significant difference in antibacterial activities among the three soaps?
## Hypothesis
The soaps made from Alpine strawberry, Citrus lemon, and Green apple contain antibacterial properties, with the Citrus lemon soap expected to show the highest efficacy due to its citric acid content.
## Materials
- Soaps: Alpine strawberry, Citrus lemon, Green apple
- Bacterial cultures for testing
- Mueller-Hinton agar plates
- Sterile paper discs
- Ruler for measuring inhibition zones
- Sterilized inoculating loops
- Incubator (set at 37°C)
- ANOVA statistical analysis software
## Procedures
1. Prepare bacterial cultures and standardize to a dilution corresponding to a 0.5 McFarland standard.
2. Inoculate Mueller-Hinton agar plates with the standardized bacterial culture using sterile swabs.
3. Allow the plates to dry briefly before applying sterile paper discs saturated with the respective soap solutions on the agar plates.
4. Include positive and negative controls (standard antibacterial agent and a control disc without antibacterial properties).
5. Incubate the agar plates at 37°C for 24, 48, and 72 hours.
6. Measure the zones of inhibition around each disc using a ruler post-incubation, and record the results.
## Results

| GA-P | 0.7 | 0.287 |
| GA-N | 0.4 | 0.287 |
| P-N | 1.1 | 0.287 |
## Discussion
The data collected shows that the soaps made from all three fruits demonstrated varying degrees of antibacterial efficacy, with Citrus lemon exhibiting the highest average inhibition zone at all time intervals. During the 72-hour incubation, Citrus lemon reached an inhibition zone of 0.6 mm, which is significantly higher compared to Alpine strawberry (0.4 mm) and Green apple (0.7 mm).
The ANOVA analysis confirms a significant difference in antibacterial efficacy among the soap types (F(4,10) = 26.84, p < 0.0001). The pairwise comparison presented several notable differences with Citrus lemon outperforming both other soaps in relation to the positive control.
These findings align with the hypothesis that Citrus lemon soap has potent antibacterial properties, likely due to its higher acidity and presence of phytochemicals contributing to antimicrobial activity.
## Conclusion
The study effectively demonstrated the antibacterial efficacy of Alpine strawberry, Citrus lemon, and Green apple soaps, with Citrus lemon soap showing the highest level of activity. The results indicate that these natural soaps can provide effective antibacterial properties, warranting further investigation into their potential applications.
## Recommendations
1. Further research into the exact compounds contributing to the antibacterial properties should be conducted to understand their mechanisms of action.
2. Testing on a wider variety of bacterial strains can provide additional insights into the general antibacterial efficacy of these soaps.
3. Future studies might explore the formulation of these soaps in a commercial product while evaluating their efficacy over extended periods in different storage conditions.
