    EVALUATION OF PLANT EXTRACTS ON BIOFILM
    (IDOSI Publications, 2016) P, Ruban; K, Gajalaksmi
    A biofilm is any group of microorganisms in which cells stick to each other on a surface and plant derived products or drugs have been used since time immemorial in health care for treatments of a variety of infectious diseases In this study, aqueous extract from different plants (Azadirachta indica, atharanthus roseus, Tectona grandis) were investigated for antimicrobial activity. The microorganism tested were Staphylococcus aureus, Bacillus subtilis,Pseudomonas aeruginosa. All species showed some antimicrobial activity against S. aureus, Pseudomonas aeruginosa in 50 µl concentration, zone of inhibition (MIC) such as 28.2, 31, 35 mm. This study showed that these plant species could be useful sources for new antimicrobials.
