Genus Lyngbya is extensively explored for antibacterial compounds among non-heterocystous cyanobacteria. Most of the non-heterocystous cyanobacterial genera are not searched for antibacterial compounds. Hence, there is a wide scope for mining of antibacterial compounds from Non-heterocystous cyanobacteria. KEYWORDS: Cyanobacteria, Non-heterocystous, Lyngbya *Corresponding Author Dr. N.
