[1] Bacillus pumilus spores—with the exception of mutant strain ATCC 7061—generally show high resistance to environmental stresses, including UV light exposure, desiccation, and the presence of oxidizers such as hydrogen peroxide.

[3] A strain of B. pumilus isolated from black tiger shrimp (Penaeus monodon) was found to have high salt tolerance and to inhibit the growth of marine pathogens, including Vibrio alginolyticus, when cultured together.

These acids contain polyglycosyl phosphates with mono- and disaccharides as their monomers that can play a role in adhesion to different surfaces like the host cells.

[7] Bacillus pumilus (ATCC 27142) may be utilized (as a biological indicator or 'BI' for short) to monitor Gamma, Electron Beam (E-beam), or X-ray radiation sterilization processes.

As such, the International Standards Organization (ISO) no longer recognizes B. pumilus as a BI method of validation or routine monitoring of a terminal radiation sterilization process for medical devices labeled as 'sterile'.
