doi: 10.1007/s10661-026-15246-9
Figure Lengend Snippet: Persistence of bacterial subpopulations in microcosms from the Alb river at two incubation temperatures (20 °C and 4 °C) and the Rhône river at 20 °C, with or without treated wastewater addition over 10 weeks. A abundance of total E. coli cells quantified using the IDEXX Colilert test ( N = 144). B Colony-forming units (CFU) of ESBL-producing E. coli grown on CHROMagar medium ( N = 140). C CFU of total ( N = 96) and D ESBL-producing ( N = 96) bacteria grown on R2A agar. RW, river water. RW + WW, river water with 5% v/v wastewater addition. Values under the detection limit (1 cell/1 CFU) for graphs A – D and missing values from the Rhône for graphs C and D are not represented
Article Snippet: River water bacteria from 100 mL of Alb river microcosms incubated at room temperature and at 4 °C at every sampling time filtered using 0.45-μm pore-size filters were cultured on R2A agar medium (Merck) for 48 h at 21 °C.
