Özet:

Microalgues that have been greatly attracted in recent years are valuable new generation raw materials that have the potential to be used in food, health, cosmetics, environment, fuel fields.In this study, aiming at the hand of diatoms, which are an important microalgues class in terms of both quantity and functions, the isolation study on water samples collected from the beaches of the Marmara Sea Mudanya was carried out and the molecular analysis of the obtained isolate was carried out in Pleurosigma sp. It has been identified. The Pleurosigma sp. When statistically interpreted by cultivating in nutrient solutions containing nitrogen, phosphorus and silicon in different concentrations, it was observed that the cell intensity of the diatom showed a clearly positive correlation with silicon and nitrogen, but its correlation with phosphorus was not clear for the selected phosphorus range. The Pleurosigma sp. Characterization studies have shown that diatom contains significant amounts of silicon structures and has a high ashes content, the fatty acid profile is combined with fatty acids that are frequently found in diatom in literature.
