In the present study, soil samples were collected from hospital nearby areas and some bacteria were isolated and purified by using spread plate and streak plate methods.  The six strains named A, B, C, D, E and F were cultured. Cultural, morphological and biochemical characterization was done to identify theses bacterial isolates. Eighteen Indian medicinal plantswere selected to examine the antimicrobial activity against the cultured species using disk diffusion method.  Methanolic extraction as well as water extract of the plant leaves and roots was prepared and phytochemical screening of these plants was performed for constituents such as flavonoids, saponins, glycosides, tannins, phytosteroid, phenols, alkaloids, etc.  Among all the plants Citrus Limon showed maximum antimicrobial activity (by inhibition zone method) against the isolated microbes.  However, the isolated microbes were susceptible to the methanolic extracts of the above mentioned plants.  In future, these plants can be further subjected to isolation of the therapeutic antimicrobials for health purposes and food applications.

Key words: Microorganism, Antimicrobial activity, Saponins, Glycosides, Tannins, Phytosteroid
