초록

This report describes the test results of decontamination of Bacillus atrophaeus spores. The spore solution at 109 cfu/mL concentration was treated with chemical decontaminants, hydrogen peroxide, DF-200, sodium dichloroisocyanurate(NaDCC), and perasasfe. DF-200 was not suitable for decontamination of the spore solution. Among them, the optimal decontamination reaction conditions of perasafe and NaDCC were established from test tube experiments in a mL-scale, and they were validated in a bio-reaction system in a L-scale. The optimal conditions of perasafe and NaDCC were 1.0 % of concentration with 5 minutes of reaction time and 0.3 % of concentration with 10 minutes of reaction time, respectively. Also, both decontaminants required adequate agitation for decontamination. The results in the bio-reaction system were similar with the results from the smaller scale using test tubes, showing that the optimal conditions from the smaller scale experiments can be applied to the larger scale.
