Fig. 4: Maximum growth rate per hour of the GmR strain at different treatments.

Values are mean ± standard deviation. (WW) SN: supernatant of the wastewater community culture. (WW) SN + fresh ABs: supernatant of the wastewater community culture with fresh antibiotics added. (WW + ABs) SN: supernatant of the wastewater community culture in the presence of antibiotics. (WW + E. coli) SN: supernatant of the focal strains and wastewater community culture. (WW + E. coli) SN + fresh ABs: supernatant of the focal strains and wastewater community culture with fresh antibiotics added. (WW + E. coli + ABs) SN: supernatant of the focal strains and the wastewater community culture in the presence of antibiotics. The antibiotics were added at gentamicin 10 µg mL−1 and kanamycin 2.5 µg mL−1. Significant differences are indicated with different letters (P < 0.05, ANOVA).
