Antimicrobial Activity of Ethanolic and Distilled Water Bark Extract of Tamarindus indica L. against some Pathogens with reference to Air Pollution at Indore

Abstract

In the present investigation the antimicrobial activity of Tamarindusindica in ethanolic and distilled water bark extract against gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis)and gram-negative bacteria(Escherichia coli and Klebsiellapneumoniae)was evaluated for different polluted areas and was compared by reference area of Indore city. Investigation showed significant activity in ethanolic bark extracts against Escherichia coli, followed by Staphylococcus aureus andKlebsiellapneumoniae in comparison to distilled water. The highest zone of inhibition (mm) was found to be at LPA againstE.coli(18mm) while comparing with polluted areas it was found to be highest at IPA i.e.15mm against Klebsiellapneumoniae . No zone of inhibition was seen in Bacillus subtilis at all polluted areas.
