Abstract: Seagrasses species in Bardawil Lake have been defined through broad quantitative sampling. From the biochemical constituent's point of view, two species namely; Cymodocea nodosa and Ruppia cirrhosa were evaluated as feed additives and antimicrobial active compounds. The obtained results showed an obvious increase in chlorophyll "a", carbohydrate and lipid contents in the C. nodosa than R. cirrhosa while protein contents was higher in R. cirrhosa than in C. nodosa. Whole plant tissues powder substance (10.0%w/v) and ethanolic extracts (200μg/ml) of C. nodosa and R. cirrhosa were evaluated against some microorganisms using pour plate technique. Powdered substance of C. nodosa was exhibited the highest antifungal activity than that of R. cirrhosa, also its ethanolic extract inhibited all of the tested bacterial isolates except E. coli. R.cirrhosa whole plant tissues powder showed antibacterial effect on all the used bacterial isolates in addition to its reduction the radial growth of Alternaria alternatium. The inhibitory effects of the whole powder and ethanolic extracts varied considerably between the assays microorganisms.
