Abstract:
The antibacterial activity of endophytic bacteria isolated from leaves of Tamarindus indica was evaluated against various gram positive and gram negative pathogenic bacteria namely Bacillus cereus, Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Klebsiella pneumoniae and Salmonella typhimurium. Results were recorded for zone of inhibition around the disc. The endophytic bacteria isolated from Tamarindus indica shown antibacterial activity as 73.33 per cent isolates inhibited growth of Staphylococcus aureus, 86.67 percent isolates inhibited growth of Escherichia coli and 86.67 percent isolates inhibited growth of Bacillus cereus. The endophytic bacteria isolated from Tamarindus indica had not shown antibacterial activity against Streptococcus pyogenes, Klebsilla pnumoniae and Salmonella typhimurium.
