Question

Decimal reduction time of bacterial spores is 23 min at 121 ⁰C and the death kinetics follow first order. One liter medium containing 10^5 spores per mL was sterilized for 10 min at 121 ⁰C in a batch sterilizer. The number of spores in the medium after sterilization (assuming destruction of spores in heating and cooling period is negligible) will be ___________×10^7.
