Microbiology: Methods for Counting Bacteria
mathbench.org.auOne way we can do this is to use a spectrophotometer. A spectrophotometer doesn't exactly count the bacteria, but it does. measure how much they interfere with a light beam, and based on that, we can use a standard curve to decide how many bacteria there are. Then we can do the scaling up trick to get the total population size.
