Study the Effect of Medicinal Plant Extracts on the Growth of Bacterial and Fungal

Abstract

Study antimicrobial and antifungal activity of three selected plants medicinal Rosemary (Rosmarinus officinalis), Ginger (Zingiber officinale) and Anise (Pimpinella anisum L.). The plants were extracted and dissolved with ethanol, and study the effects of them against growth of some bacterial pathogens isolates like (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Staphylococcus aureus, Micrococcus roseus and streptococcus pygenes) also study the effects of this plants extracts against the growth of some fungal like Candida tropicalis, Candida albicanus Penicillium sp. Fusarium sp. Rhizopus sp. Aspergillus niger . The results showed that all plants extracts exhibited antibacterial activity and antifungal activity against the tested isolates in tow concentration (10^-1 and 10^-3). S. aureus was the most bacterial species effected inhibition zone (18 mm) with Rosemary and the lowest species of bacteria effected and show minimum inhibition zone (8 mm) was Anise against Pseudomonas aeruginosa, on the other hand the highs inhibition zone against fungi was recorded with Anise so (18 mm) which inhabit growth of Aspergillus niger and the minimum inhibition zone (8 mm) show with Ginger against C. albicanus.
