Salinity is one of the most common environmental stress factors that adversely affect plant growth and crop production in cultivated areas worldwide. Herbal or ‘alternative’ medicine is gaining popularity and scientific research about wheat grass as a “functional food” is becoming more available and popular. Wheat grass, Triticum aestivum L. has a long history and is widely used as a health food supplement. It is found to be used as a treatment for minor ailments and serious life threatening issues, and also as a preventative dietary supplement and therapeutic drugs. Current study was aimed at evaluation of antimicrobial properties of two varieties of T. aestivum L. [cv. Tosunbey (drought tolerant) and cv. Sultan 95 (drought sensitive)] which grown in three different condition [(1) control; not treatment with salt or acetyl salicylic acid; (2) treatment with sea water; (3) sea water and pre-treatment of seeds with acetyl salicylic acid]. The antimicrobial activity of the ethanol extracts of two varieties of T. asetivum were assayed against Escherichia coli NRRL B-3704, Pseudomonas aeruginosa ATCC 27853, Proteus vulgaris ATCC 13315, Acinetobacter baumanii ATCC 19606, Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25923, S. haemolyticus ATCC 43252 and Candida albicans ATCC 10231 test microorganisms by agar disc diffusion method and micro broth dilution methodsThe results of showed that the ethanol extracts from the different treatments studied showed antimicrobial activities, with the diameters of the inhibition zone ranging from 8 to 13 mm and 2.5 to 20 µg/mL, respectivelyBut, the highest antimicrobial activity against P. aeruginosa ATCC 27853were demonstrated by the extract of T. aestivum cv. Sultan 95 which grown in sea water and pre-treatment of seeds with acetyl salicylic acid.
