Decontamination Performance for Biological Agent Simulants

At Sandia National Laboratories (SNL) we tested the decontamination performance of the Sandia Decon Formulation for biological agent simulants. The biological agent simulants used were Bacillus globigii (a simulant for anthrax spores), Erwinia herbicola (a simulant for vegetative bacterial cells), and MS-2 bacteriophage (simulant for viruses). For the B. globigii spores, a 7-log kill was achieved in an hour. Likewise, similar results for the vegetative bacterial cells and the viruses were achieved in 15 and 30 minutes respectively.

We confirmed our biological agent simulant test results by contracting with a facility licensed to perform live agent testing of anthrax. A solution test was performed (i.e., the spores were added to our decontamination solution). As evident in the figure below, a 7-log kill was achieved during a one hour exposure period.
