If inadequate information regarding the product or service exists to evaluate its probable progress inhibiting activity.
Cultures employed for the strategy suitability test might be bought commercially, ready to use, or can be geared up and taken care of domestically. Both technique involves quantitative verification of precise CFU’s inoculated at time of use.
