You have found that the D-value (decimal reduction value) of an antimicrobial agent to be 4 minutes when the agent was exposed to a bacterial culture having an initial total viable cell count of 10° CFU/mL. After 4 minutes upon addition of the antimicrobial agent, what would have been the total viable count of the culture in this experiment? A) O 10° CFU/mL B) O 108 CFU/mL C) O 10° CFU/mL D) O 10! CFU/mL

Expert Solution
Step 1

In sterilization techniques, D-value or decimal-reduction value refers to the time taken, under specified conditions, to get one decimal logarithm reduction in the initial bacterial population. It means the time taken to kill 90% of viable microorganisms.
