Antimicrobial activities of fatty acid methyl esters (FAME) of Scenedesmus bijugatus var. bicellularis.

In our collaborative study, we evaluated the efficiency of microalgal (Scenedesmus bijugatus var bicellularis) fatty acid methyl esters (FAME) as an antimicrobial agent against Staphylococcus aureus, Escherichia coli and Candida albicans. The FAME analysis by Gas Chromatograph (GC) with Flame Ionization detector (FID) revealed the presence of 30 different methyl esters. Out of these, various pharmacologically active FAME like Stearic acid methyl ester (C18:0) (0.6 % w/w), Oleic acid methyl ester (C18:1) (1% w/w), Linoleic acid methyl ester (C18:2) (1.40% w/w), Linolenic acid methyl ester (C18:3) (6.26%), Eicosapentanoic acid methyl ester (C20:5) (1.13 % w/w), Erucic acid methyl ester (C22:1) (1.03% w/w) and Docosahexenoic acid methyl ester (C22:6) (2.27 % w/w) exhibited both anti-bacterial and anti-candidal activity. To the best our knowledge, this is the first report on the antimicrobial activity of FAME from microalgae.
