38ANTIBIOTIC ACTIVITY OF CYANOBACTERIA ISOLATED FROM SALT PANS OF KANYAKUMARI DISTRICT AGAINST HUMAN PATHOGENIC BACTERIAMethanol extracts of salt Pans Cyanobacteria have been investigated for in vitro antibacterial activity against Escheriachia coli, Streptococcus aureus, Salmonella typhi, Klebsiella pneumonia, Streptococcus facecalis and Bacillus subtilis using agar diffusion and Minimum inhibition concentration. The Cyanobacteria namely, Spirulina major, Oscillatoria salina and Plectonema terebram showed significant antibacterial activity than other tested salt Pan Cyanobacteriaregihelen7@yahoo.co.ukResearch412014Cyanobacteria,Antibacterial activity,Salt Pans,Human pathogensHelen Diana Y,M Reginald Appavoo,B ParthipanDepartment of Botany and Research Centre, S.T.Hindi College, Nagercoil, Tamil Nadu, India,Department of Plant Biology and Plant biotechnology, Scott Christian College, Nagercoil, Tamil Nadu, Indi,Department of Botany and Research Centre, S.T.Hindi College, Nagercoil, Tamil Nadu, India
