Background and purpose

Today, due to the dangers of chemical preservatives in food, alternative and safe methods such as the use of natural extracts of natural plants have increased. The aim of this study was to evaluate the antibacterial effects of Kenar fruit extract on the bacteria of Salmonella, Shigella, Escherichia coli and Bacillus cereus.

Materials and Methods

We prepared Kenar fruit extract by soaking or immersing in methanol. After concentrating by rotary device, we prepared 9 concentrations of the extract serially, then performed antibiogram by well method and determined MIC and MBC. We also used volumetric-volumetric solution of methanol and dimethyl sulfoxide in equal proportions as negative control and control disks and standard commercial antibiotics as positive control.

Results

Based on the results, the diameter of inhition zone for dropletsfor Shigella, Salmonella, Bacillus cereus and Escherichia coli at a concentration of 80 mg/mL of methanolic extract of the plant was 24, 17, 59 and 19 mm, respectively. It was also found that methanolic extract of Kenar fruit had very good antibacterial effects on gram-positive bacterium Bacillus cereus compared to other target bacteria (which are gram-negative) and had significant growth inhibition and bactericidal effects at very low concentrations.

Conclusion

The results showed that methanolic extract had very favorable antibacterial effects against four target bacteria. Therefore, it can be said that the compounds of methanolic extract of this plant can be used as important components of various products in the food, pharmaceutical, cosmetic and health industries.
