10. A culture of Escherichia coli is heated at 60°C and a series of samples taken at intervals to determine the numbers of survivors. From the data we can calculate the D-value for this strain. The D-value: A. Tells us how long we need to heat the bacteria at 60°C to achieve the SAL B. Tells us how long the bacteria needs to be heated at 60°C to achieve a 10-fold reduction in viable counts C. Allows us to predict how quickly the E. coli would die at 60°C D. Allows us to predict how quickly E. coli would multiply at 60°C E. Tells us the relationship between temperature and rate of killing
