Evaluation Of Antibacterial Activity Of Some Lichen From Ravangla, Sikkim, India.
Antibacterial activity of acetone, methanol and aqueous extract prepared from some lichen lessThan br / greaterThan species were evaluated against five bacterial strains viz. Staphylococcus aureus, Escherichia lessThan br / greaterThan coli, Vibrio cholerae, Shigella dysenteriae. Shigella flexneri The aqueous, methanol and acetone lessThan br / greaterThan extracts exhibited a variable range of antibacterial activity to bacterial strains. The acetone and lessThan br / greaterThan methanol extracts of all investigated lichens showed selective antibacterial activity. The lessThan br / greaterThan methanol extracts were usually the most active against test organisms. An aqueous extracts of lessThan br / greaterThan investigated lichens were found to be inactive against all tested bacteria.
