The 12 marine cyanobacterial species were isolated from Adirampattinam coast, and cultured in ASN
III media. Based on their growth characteristic, three species namely Oscillatoria sp., Phormidium sp. and
Lyngbya majuscule were selected for antibacterial assay against the human pathogenic bacteria such as
Streptococcus mutants, Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis and Klebsiella
pneumoniae. The experiments for the inhibition activity on human pathogenic bacterial strains were carried out
at different concentration levels (250, 500 and 750 μg mL-1) of crude extract of 3 species of Cyanobacteria.
Among the 3 cyanobacterial species extracts, Oscillatoria sp. showed the maximum inhibition (20 nm) against
pathogen strain compared to other species and the minimum inhibition activity (7.2 nm) was observed in the
extract of L. majuscule. The species Oscillatoria showed maximum zone of inhibition against pathogenic
bacterial active revealed the potential of cyanobacterial extract.
