Decontamination of biological agents utilizes hydrogen peroxide($H_2O_2$) for its effectiveness and safeness. Bacillus anthracis is a major target for $H_2O_2$ decontamination. To assess the effect of $H_2O_2$ on B. anthracis and identify biomarkers for decontamination, whole transcriptomic profiling of $H_2O_2$-treated B. anthracis was performed. Here we identified deregulation in stress response genes, transcription factors and cellular homeostasis genes. We also found that expression of antisense RNAs increased in B. anthracis during decontamination. We postulate that B. anthracis prioritizes survival and adaptation in response to $H_2O_2$ treatment by changing its gene expression pattern.
