Abstract:
Geobacillus stearothermophilus spores play an essential role in the pharmaceutical and food industries as bioindicators (BI) to evaluate inactivation effects of hydrogen peroxide in processing and packaging lines' sterilization. Unstandardized, inconsistent BI production, as is the case for currently available commercial BI, can lead to variable resistances and incorrect test results. The solution to this problem could be the standardization of BI spore production. This study assessed the effect...     »
