Antibacterial assay of cyanobacteria in invitro conditions and its valuable applications

Cyanobacteria are aquatic and photosynthetic they survive in fresh water ponds sewage water. Since these cyanobacteria quite small unicellular, often grow large colonies more enough to see by naked eye. produce bluish green colour pigments as phycocyanin, phycobiliproteins carotenoids. It may surprise you know that still around one of the largest most important groups bacteria on earth. The cyanobacterial ethanolic extracts Oscillatoria formosa, subbrevis, princeps, sancta fischeri showed effective antibacterial activity against pathogenic microorganisms like Streptococcus pyogenes, pneumoniae, Clostridium perfringes, Salmonella typhi Vibrio cholerae. curviceps, Lyngbya majuscula Spirulina subsalsa rich source bioactive compounds with antibacterial, antifungal, antialgal antiviral properties. Some Synechococcus elongatus have ability accumulate polyhydroxyalkanoates which be used bioplastics. In addition applications also useful agricultural practices Nostoc commune Anabaena aequalis biofertilizers. eukaryotic algae Chlorella vulgaris, Botryococcus braunii Schizochytrium limacinum oil content for ecofriendly production biodiesel.
