The connection between Sea of Marmara biodiversity and mucilage occurrenceincidenceArzu Karahan1, Selin Deliceırmak2, Mertcan Esti1, Evrim Kalkan Tezcan1, Esra .ztürk1, Hasan .rek11Middle East Technical University, Institute of Marine Sciences, 33731, Erdemli, Mersin, Turkey2Near East University, Faculty of Arts and Sciences, Department of Molecular Biology and Genetics, Nicosia,Turkish Republic of Northern CyprusMucilage shapes because of the sudden death of certain bacteria and/or phytoplankton right aftertheir bloom. During the processes, they do not sink and decay quickly; as a result, polysaccharides areproduced, and the hydrocarbons increase in the seawater. Mucilage is also formed by the benthicfilamentous macroalgae besides the pelagic species in the water column. The mucus-like structurenegatively affects the organisms by either accumulating on the soft and hard bottom of the seabed orby directly covering the organisms. This study aims to determine the taxa responsible for mucilageformation in the Sea of Marmara using 16S amplicon sequencing and metabarcoding techniques (18Sand ITS) and to understand their possible effects on the Sea of Marmara ecosystem. Within this scope,the prokaryotic (archaea and bacteria) and eukaryotic diversity in 30 mucilage samples taken from 23stations representing a large part of the Sea of Marmara are studied using the Next GenerationSequencing technique. In the study, the prokaryotic and eukaryotic diversity of the mucilage in the.ınarcık Pit and Izmit Bay stations has been revealed by now. Bioinformatic analysis of the other 28samples is ongoing. Interpreting the genetic data with the physical and chemical parameters, thosecollected from the mucilage sampling stations within this study scope and the other stations representingthe whole Sea of Marmara are essential to reveal the environmental triggers that cause mucilageformation or formation induced by mucilage.
