Journal ArticleDOI
Assessment and interpretation of bacterial viability by using the LIVE/DEAD BacLight Kit in combination with flow cytometry.
Michael Berney,Frederik Hammes,Franziska Bosshard,Franziska Bosshard,Hans Ulrich Weilenmann,Thomas Egli,Thomas Egli +6 more
TL;DR: It is shown here that the application of propidium iodide in combination with a green fluorescent total nucleic acid stain on UVA-irradiated cells of Escherichia coli, Salmonella enterica serovar Typhimurium, Shigella flexneri, and a community of freshwater bacteria resulted in a clear and distinctive flow cytometric staining pattern.
Journal ArticleDOI
Key roles of pH and calcium metabolism in microbial carbonate precipitation
Frederik Hammes,Willy Verstraete +1 more
TL;DR: In this article, the general mechanism of microbial carbonate precipitation is reviewed and an alternative view on the role of calciummetabolism in this process, as well as on theoccurrence of species- and environment-specific calcification.
Journal ArticleDOI
Flow-cytometric total bacterial cell counts as a descriptive microbiological parameter for drinking water treatment processes.
Frederik Hammes,Michael Berney,Yingying Wang,Yingying Wang,Marius Vital,Marius Vital,Oliver Köster,Thomas Egli,Thomas Egli +8 more
TL;DR: It is shown that total cell concentration measured with FCM is a rapid, easy, sensitive and importantly, a descriptive parameter of several widely applied drinking water treatment processes.
Journal ArticleDOI
Strain-Specific Ureolytic Microbial Calcium Carbonate Precipitation
TL;DR: It is shown that strain-specific calcification occurred during ureolytic microbial carbonate precipitation, mainly due to differences in urease expression and the response to calcium.
Journal ArticleDOI
Measurement and interpretation of microbial adenosine tri-phosphate (ATP) in aquatic environments.
Frederik Hammes,Felix Goldschmidt,Marius Vital,Marius Vital,Yingying Wang,Yingying Wang,Thomas Egli,Thomas Egli +7 more
TL;DR: The results support the use of ATP analysis for both routine monitoring and research purposes, and contribute towards a better interpretation of ATP data.
