Microbial growth, bacterial community shifts, and oxygen concentration in non-carbonated natural mineral waters 1 and 2 after bottling. In years 2011 and 2012, waters 1 and 2 were filled in PET bottles and were monitored during 56 days of storage. Total planktonic cell counts (gray bars) and dissolved oxygen concentrations (red) are shown as mean ± standard error (n = 3). To ensure bottle stability during packaging and delivery, bottling is performed using compressed air with an initial pressure of 1.5 bar for water 1 and 2.2 bar for water 2. W well water. Temporal changes in bacterial community composition in the water (plankton) and on the inner bottle wall (biofilm) were analyzed by 16S rRNA gene amplicon sequencing. Bar charts only show phyla with > 5% relative abundance in at least one sample. Proteobacteria are shown as individual families
