Phenotypic analysis of catalase activity. Monitoring the decrease in absorbance at 240 nm of crude extract of A. baumannii AB5075 and derivate strains cultured in LB or LB supplemented with 3.5% HSA. The mean ± SD is informed of three independent experiments. Statistical significance (P < 0.05) was determined by ANOVA followed by Tukey’s multiple comparison test, one asterisks: P < 0.05; two asterisks: P < 0.01 and three asterisks: P < 0.001. This figure was performed using GraphPad Prism version number 9 (GraphPad software, San Diego, CA, USA, https://www.graphpad.com/).
