Urease assays. a,b Bacteria-growth curves were determined at different pH values (a pH=5.5, b pH=7.0). c Urease activity determination of specific bacteria under different pH values (IU/L: international active units per 1 L bacterial suspension). d The ratio of bacterial ureC to 16S rRNA transcripts. Kp: K. pneumoniae; Kox: K. oxytoca; Cf: C. freundii; Mm: M. morganii. Error bars represent the standard error of the mean. Different letters indicate statistical significance (p < 0.05). “*,” “**,” and “***” represent statistical significance at p < 0.05, 0.01 and 0.001, respectively
