Pathogenic microbes secrete various enzymes to facilitate their survival within the host which may have direct/ indirect role to play in bacterial virulence. In the present work, extracellular amylase producing bacteria were isolated from air, water and soil samples by serial dilution and plating method. Twenty three bacterial isolates obtained were screened for amylolytic activity, out of which only 5 isolates showed amylolytic activity viz: Streptococcus sp., Staphylococcus sp., two Bacillus sp. and Veillonella sp., which were identified by phenotypic characterization. The results revealed that Streptococcus sp. exhibit beta haemolysis on blood agar and had the potential to produce 120 EU extracellular amylase after 48 hours. This is reported here for the first time for production of extracellular amylase. This enzyme might be a regulatory/ signaling molecule and thus be an attractive drug target in the treatment of bacterial infections.
