A batch sterilizer is being operated at 121 °C for sterilizing a medium containing microbial cells. Assume that the thermal inactivation of cells is a first order process with a death rate constant of 0.69 min
at 121 °C. If the initial concentration of microbes in the medium is 10
cells m
, the time taken to reduce the microbial load to a final concentration of 10 cells m
is ________ min. (rounded off to the nearest integer)Log in to check the answer
