Evaluation of antimicrobial activity of Malus domestica fruit extract from Kashan area

Abstract

Objective: Many species of plants present noticeable potency against human bacterial and fungal pathogens. <br/>Materials and Methods: In the current study, antimicrobial activity of the fresh fruits of 4 cultivars (A to D) of <em>Malus domestica </em>cultivated in the Qamsar area of Kashan, Iranwas investigated. The disk diffusion and minimal inhibitory concentration (MIC) evaluation antimicrobial activity tests were performed. <br/>Results: The samples showed moderate antimicrobial activities with inhibition zones from 11 to 16 mm in these tests. Cultivar D with inhibition zones of 16, 14, and 12 mm for <em>E. coli</em>, <em>S. epidermidis</em> and <em>K.</em> <em>pneumoniae</em>, respectively exhibited the best results in these tests. Cultivar A also showed a zone of inhibition of 11 mm against <em>P.</em> <em>aerouginosa</em>. <br/>Conclusion: Moderate antimicrobial activities were observed for the studied apple cultivars. <br/>
