Question

A antimicrobial method that reduced a population from 10000 to 100 cells in 10 minutes has a decimal reduction time of _______.

Answer 1

Answer:

Decimal reduction time $= 990$ cells per minute

Explanation:

Given -

Initial population of cells $=10000$

Final population of cells  $=100$

Total change in population of cells is equal to final population of cells minus the initial population of cells.

Total change in population of cells $= 10000-100\\= 9900$

Total time taken by cell to reduce $= 10$ minutes

Decimal reduction  time

$= \frac{9900}{10} \\= 990$ cells per minute
