The slight die-off generally observed in some commercial bellow samples is either due to desiccation of the inoculum as a result of the rubber's high porosity, or the presence of traces of additives, such as mercaptobenzothiazole, used as an accelerator for the vulcanization process, which exhibit antimicrobial properties.
