Isolation and Screening of Endophytic Microorganisms Isolated from Leaves of Three Medicinal Plants Growing in Marsa Matrouh

This study aimed to investigate the biodiversity of endophytic microorganisms isolated from leaves of Lycium shawii, Urginea maritima and Nicotiana glauca medicinal plants growing in Marsa Matrouh. After 21 days incubation period on different media viz potato dextrose agar, starch casein agar, nutrient agar and yeast peptone dextrose solid media. The results showed twenty one endophytic microorganisms have been isolated from the three selected plants. Fungal endophytic isolates were dominant isolates with eight isolates followed by actinomycetes, yeast and bacteria with 6, 5 and 2 isolates, respectively.
