Introduction: Microalgae are considered productive organisms due to their chlorophyll and their richness in fatty acids and various pigments has diversified their use and increased the importance of their investigation from an ecological and biotechnological point of view. This study aimed to investigate water quality, diversity of microalgae, and the possibility of commercializing important microalgae species.
Materials & Methods: Sampling was carried out from the Kelvans Dam located in West Azerbaijan at 4 stations. The algae samples were cultured in a Walne medium, and the identification of microalgae was performed using identification keys. Due to the high similarity of some microalgae species, molecular methods were used to accurately identify microalgae at the species level. Two commercially important species belonging to the Haematococcaceae and Scendesmaceae families were isolated among these algae, identified using molecular techniques through ITS sequencing, and their fatty acid profiles were examined.
Results: The initial investigation successfully identified several genera and species including Scendesmus sp., Haematococcus sp., Navicula sp., Pandorina sp., Scendesmus dimorpha, and Pediastrum boryanum. After molecular analysis, the sequences related to Haematococcus lacustris and Scendesmus sp. were recorded in the NCBI GenBank with codes ON975001.0 and ON955512.1, and these species were precisely identified. The examination of the fatty acid profiles of these two species showed that they have high nutritional value for use in various industries. Additionally, in this study, the use of ITS marker as an accurate and reliable method for identifying microalgae species was suggested.
Conclusion: The physicochemical characteristics of the Kelvans Dam water also showed that the water of the region has the potential to store fish larvae and mass-cultivate microalgae while adhering to environmental principles. |
