Antimicrobial Organic and Aqueous Extracts of the Leaves of Thymus Numidicus, Collected from Bouira (Algéria)

Abstract

Abstract-Aromatic and medicinal plants are an important source of antimicrobial molecules, especially in volatile extracts. The genus Thymus is considered among the richest in essential oils. In this context, this work focuses on the extraction of the organic compound by steam soxlhet of a species endemic; Thymus numidicus L. from Bouira. On the other hand, the determination of the antimicrobial activity of this organic compound. In this study, we have used these microorganisms; Echerichia coli, Pseudomonas fluorescence, Staphylococcus aureus, Aspergillus fumigatus, Candida albicans, and Aspergillus niger. The antimicrobial activity was tested by agar diffusion technique and calculation of the minimum inhibitory concentrations (MICS). The results showed a very good antimicrobial activity on the bacteria and no effect on yeasts and molds tested.
