Comparative analysis of bioactive compounds and antimicrobial activity in marine cyanobacteria

A comparative study of bioactive compounds in two marine cyanobacteria species, Oscillatoria acutissima and Oscillatoria simplicissima, grown in F/2 media was performed by estimation of many of bioactive compounds after 12th days, The greatest level of Phenolics and tannins was observed in Oscillatoria acutissima. Methanolic extracts of two species of cyanobacteria demonstrated diverse antimicrobial activity toward various human pathogenic microbial species which were associated with their bioactive components. Two species of cyanobacteria were observed to be the most active one in relation to all examined pathogenic microorganisms. The methanolic extracts of the algae were chemically distinguished by gas chromatography mass spectroscopy "GC-MS". Based on the results obtained, the two species of marine cyanobacteria can be a renewable provider of beneficial bioactive complexes for health and nutritional products.
