Gas Chromatography- Mass Spectrometry Analysis and Antibacterial Activity of Fatty acid Mixture of Spirulina platensis

Spirulina platensis is a micro alga which contains many essential fatty acids, like gamma linolenic acid, stearic acid, myristic acid, linoleic acid, heptadecanoic acid etc. The composition of individual fatty acids had been found out through GC-MS analysis based on their retention time and molecular weight. Winterization procedure was used for the extraction of fatty acid mixture. Fatty acid mixture had been screened for antimicrobial activity using agar diffusion method against four bacterial species. The mixture showed comparable activity with the standard.
