Comparison of fatty acid profiles of different strains of diatom Cyclotella meneghiniana Kützing from the salt lake Tahilt-Nuur (Mongolia)

Diatoms are a widespread group of microorganisms, many of which are able to accumulate significantamounts of long-chain and polyunsaturated fatty acids. 5 strains of Cyclotella meneghiniana were isolated during the studyof diatom flora in the salt lakes of Mongolia. The taxonomic status was confirmed by morphological and molecular genetic studies, and the features of the fatty acid composition were also established. We found that Cyclotella meneghinianastrains are producers of long-chain polyunsaturated omega-3 fatty acids and are of interest for further biotechnologicalapplications.
