Bacteriostatic activity of con a lectin from Canavalia ensiformis.

ABSTRACT

The aim of this work was to explore the therapeutic applications of Con A lectin from Canavalia ensiformis and to explore its antibacterial activity. Activity of lectin was quantified by their ability to agglutinate erythrocytes using Hemagglutination assay. Characterization and purity of Con A lectin was evaluated by using SDS-PAGE analysis. The reversal of hemagglutination activity of lectin was evaluated by using the sugars namely; mannose, galactose, lactose, fructose, glucose. The antibacterial activity of lectins was tested against Streptococcus mutans, Staphylococcus aureus, Bacillus subtilis, Escherichia coli using pour plate method. Amoxycillin was used as standard. At 250mg/ml concentration Con A lectin showed good bacteriostatic activity.
