20.500.12556/RUL-134833 Water-transmitted fungi are involved in degradation of concrete drinking water storage tanks Global warming, globalization, industrialization, and the rapidly growing population at present increasingly affect the production of safe drinking water. In combination with sustainable bio-based or recycled materials, used for water distribution systems, these factors promote emerging pathogens, including fungi. They can proliferate in oligotrophic water systems, affect the disinfection process, degrade building materials, and cause diseases in humans. In this study, we explored fungalbased degradation of modern concrete water storage tanks and the presence of fungi in chlorinated drinking water at the entrance and exit of the tanks. The degradation potential of isolated 52 fungal strains and their growth at different oligotrophic conditions was tested in vitro. Forty percent of strains grew at extremely oligotrophic conditions, and 50% classified as aerophilic. Two-thirds of tested strains produced acids, with Penicillium strains as the best producers. Only 29.7% of the strains were able to grow at 37 °C, and none of them was isolated from drinking water at consumers’ taps. Although not yet part of the guidelines for building materials in contact with drinking water, fungi should be taken into consideration in case of visible degradation. Their number of consumers’ endpoints should be checked to exclude possible health risks for consumers. degradation chlorination drinking water environmental factors fungal contaminants growth of fungi materials in contact with drinking water water storage tanks razgradnja klorinacija pitna voda okoljski faktorji glivni patogeni rast gliv materiali v stiku s pitno vodo vodohrani true false true Angleški jezik Slovenski jezik Članek v reviji 2022-02-03 16:05:37 2022-02-03 16:05:37 2022-09-14 04:10:13 0000-00-00 00:00:00 2021 0 0 16 str. iss. 1, art. 160 Vol. 9 Jan. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 577 2076-2607 10.3390/microorganisms9010160 48801539 RAZ_Novak_Babic_Monika_2021.pdf RAZ_Novak_Babic_Monika_2021.pdf 1 F53EFF21691CC52157FFF2510D438F8D a3b9a40e7c90b81e8b1a8a11afbf80e89fa30ed9e37f0ef52069d2ab7adec09e 033d0fa3-8503-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153513 https://www.mdpi.com/2076-2607/9/1/160 1 866fa074-8502-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153512 Biotehniška fakulteta 0 0 0
