This lectin was named GVL, agglutinated rat, rabbit, goat, chicken and human ABO erythrocytes.The antibacterial activity of this algal lectin was studied using disc diffusion method. GVLexhibited potent antibacterial activity against bacteria such as E.coli,S.pyogenes,S.aureus,E.faecalis,B.subtilisandcoagulase-negative Staphylococci(CoNS)by disc-diffusion method.Also,the results were compared with standard antibiotic Ampicillin. These findings indicate that GVL is having therapeutic applications with great importance in clinical microbiologyenMarine algae, Gracilaria verrucosa,gel filtration chromatography,antibacterial activity, disc diffusion methodArticle
