20.500.12556/DiRROS-19496 Sequestration of polystyrene microplastics by jellyfish mucus The worldwide microplastics pollution is a serious environmental and health problem that is currently not effectively mitigated. In this work we tested jellyfish mucus as a new bioflocculent material capable of sequestration of polystyrene microplastics in aqueous environments. Mucus material was collected from different jellyfish species and was used to trap fluorescently tagged polystyrene microspheres. The efficiency of removal was tested using varying concentrations of microplastics and mucus. The interaction between the microplastics and mucus was determined by viscosity measurements and confocal laser scanning microscopy. Different mucus preparation methods were also tested: freshly prepared, mechanically sheared, freeze-thawed, freeze-dried, and hydrolyzed mucus. The results demonstrate that jellyfish mucus can efficiently sequester polystyrene microplastics particles from the suspension. The fraction of the removed microplastics was highest with freshly prepared mucus and decreased with freeze-thawing and freeze-drying. The mucus ability to sequester microplastics was completely lost in the hydrolyzed mucus. The results imply that the intact jellyfish mucus has the potential to be used as a biopolymer capable of removing microplastics material. mikroplastika polistiren meduze sluz viskoznost mikroskopija true false true Angleški jezik Slovenski jezik Neznano 2024-07-18 03:53:19 2024-07-19 10:55:16 2024-07-20 04:03:06 0000-00-00 00:00:00 2021 0 0 Soavtorji: Katja Klun, Iztok Dogsa, Ana Rotter, David Stopar; Nasl. z nasl. zaslona; Opis vira z dne 21. 7. 2021; Št. članka 690749; str. 1-11 Vol. 8 Jul. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-07-15 504.5:593.7 2296-7745 10.3389/fmars.2021.690749 70901251 https://www.frontiersin.org/articles/10.3389/fmars.2021.690749/full 1 c1ee84cc-4497-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=26897 RAZ_Lengar_Ziva_2021.pdf RAZ_Lengar_Ziva_2021.pdf 1 55881B044C46E979970A870728963478 a459197db2e4dee77e809d5e280a98a2303d6dcac59cd1e91d23cdc304dd7154 1dc02130-459c-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=26979 Nacionalni inštitut za biologijo 0 0 0
