20.500.12556/RUL-134192 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. jellyfish mucus microplastics polystyrene viscosity microscopy mikroplastika polistiren meduze sluz viskoznost mikroskopija true false true Angleški jezik Slovenski jezik Članek v reviji 2021-12-28 12:13:53 2021-12-28 12:13:53 2022-09-13 03:53:49 0000-00-00 00:00:00 2021 0 0 11 str. article 690749 Vol. 8 Jul. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 504.5:593.7 2296-7745 10.3389/fmars.2021.690749 70901251 RAZ_Lengar_Ziva_2021.pdf RAZ_Lengar_Ziva_2021.pdf 1 03776279ED87ABD9CC1C714FB36FABFB b794d60f098f57325938f8e16768f771eb2577e5d31d8b1c164ea5dfd5f31451 aad864c9-67d1-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152530 https://www.frontiersin.org/articles/10.3389/fmars.2021.690749/full 1 17f5aaa5-67cf-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152529 Biotehniška fakulteta 0 0 0
