In current investigation exopolysacharides are produced from the Trametes sp. and antibacterial activity of exopolysaccharides (EPS) was studied. The antibacterial effect of EPS was observed that they were most effective against gram-positive bacteria, especially B. subtilis and S.aureaus with a zone of inhibition 24 mm and 28 mm, respectively, at a concentration of 80 mg/ml. Moreover, with the increasing concentration, the EPS showed significant increase in antibacterial activity. The activity was lowest in the inhibition of gram-negative bacterium, E. coli and P aerogenosa at a low concentration whose inhibition zones are between 5 to 15mm.
