Although climate warming-induced reduction in snow cover makes technical snowmaking inevitable moderate climatic regions, it causes hydrological, health-related and environmental concerns. This study analyzed culturable bacteriological indicators of water quality, presence concentration antimicrobials, genes determining bacterial antibiotic resistance (ARGs) next-generation sequencing-based community composition diversity resource five ski resorts. Numbers bacteria (E. coli, fecal...

Although climate warming-induced snow cover reduction, as well the development of ski tourism in hot and dry countries, is shifting industries toward use technical snowmaking, its raises hydrological, health-related, environmental concerns. This study was aimed at enhancing our current understanding impact snowmaking on environment human health. Culturable bacteriological indicators water quality (Escherichia coli, fecal enterococci, Salmonella, Staphylococcus), presence concentration...

Abstract Mountain regions in Poland are among the most frequently visited tourist destinations, causing a significant anthropogenic pressure put on local rivers. In this study, based numbers of 9 microorganisms, content 17 antibiotics and physicochemical parameters, we determined pollution gradient six sites along Białka, typical mountain river southern Poland. The E.coli / Staphylococcus ratio varied evidently between polluted non-polluted sites, indicating that possible utility parameter...

Antibiotics are emerging pollutants of great concern, due to detrimental effects their sublethal concentrations on microbial communities. Monitoring antibiotics’ presence and in the aquatic environment is fundamental importance management water resources. This study was aimed at filling knowledge gap terms concentration antibiotics surface groundwater one mountain regions southern Poland. The detailed aims included assessment whether there spatial and/or temporal trends antibiotic occurrence...

Sugar esters are bioactive compounds derived from renewable resources. They consist of a sugar moiety with attached non-polar part – usually fatty acid. These find uses in cosmetic, food and pharmaceutical industries as surfactants due to their physicochemical antimicrobial activities. In this study we have produced acids for ester synthesis bacterially polyesters, namely polyhydroxyalkanoates (PHAs). We developed methodology decorate PHA monomers fluorinated moiety. With aid biocatalysis...

This study shows microbiological contamination of water in two main Podhale rivers, whose resources are used for the production artificial snow, and resulting snow contamination. Thirty-one E. coli strains were isolated from at ski stations studied region, their antimicrobial resistance was determined, presence extended spectrum β-lactamase (ESBL) genes searched for. The results indicate that waters both rivers severely contaminated, with, among others, thermotolerant coli. most frequently...

In recent years water demand drastically increased and this is particularly evident in tourism-burdened mountain regions. these areas, the climate neutral circular economy strategies to minimize human impact on environment can be successfully applied. Among strategies, treated wastewater reuse retaining storage reservoirs deserve particular attention. This study aimed determine if recycled produced with two systems, membrane bioreactor treatment plant (MBR) UV-light effluent disinfection a...
