Artificial geothermal water systems are an efficient and low-cost alternative to natural ecosystems for phototrophic microorganism biomass production on industrial scale. Our study focused the investigation of mat-forming cyanobacteria produced in artificial pool with a source from hot spring Uniejów, Poland. The microorganisms inhabiting this ecosystem tolerate high salinity (approximately 50 ‰) temperature (45-55.2 °C) water. structure, composition, growth rates cyanobacterial mats were investigated under laboratory conditions. We tested whether harvested habitat represent safe vital biomolecules applications. found that layered consisted simple filamentous cyanobacteria, mainly genera Leptolyngbya, Thermoleptolyngbya, Anagnostidinema. In isolated we did not detect commonly studied cyanotoxins (i.e., ATX-a, BMAA, CYN, MC, SXT) could pose direct risk human health lead indirect risks through contamination bioproducts. extracts filtrates strains reduce survival Daphnia. addition, temperatures 40-50 °C pH values 7.2-7.7 optimal mat formation dominant cyanobacteria. case Desertifilum dzianense strain, highest yield was noted at 26 °C. summary, our indicates powered by waters Uniejów have strong potential as bioresources different
