Antibacterial Activity of Actinomycetes Isolated from Different Habitats of Hadhramout- Yemen
Journal Title: Haya: The Saudi Journal of Life Sciences - Year 2018, Vol 3, Issue 1
Abstract
Abstract:A total of 70 actinomycetes strains were isolated from dams and caves of Hadhramout –Yemen and screened for their anti-bacterial activity based on their color and activity against bacterial pathogens. Twenty isolates have shown activities against pathogenic bacteria.Fourteen isolates (70%) showed activity against Bacillussubtilisby agar disk diffusion, twelve isolates (60%) showed activity against Staphylococcus aureus and fifteen isolates (75%) showed activity against Pseudomonasaeruginosa. The activity was minimal against Escherichia coli, having only 8 isolates (40%).Nine isolates were highly active with an inhibition zone more than 25 mm in diameter.Most of the isolates inhibited growth of tested Gram negative and Gram positive bacteria. Keywords:Cave soil, Dam soil, antibacterial,actinomycetes, and pathogenic bacteria.
