1. You will be able to use turbidity as a means of determining cell growth in future experiments. Using the plot of absorbance versus cell count derived in this exercise, you will be able to approximate actual cell counts in future exercises with Escherichia coli. Why can't you use this same plot (or standard curve) for other bacteria? 2. What are the advantages of estimating microbial numbers or biomass by this method? 3. What might be some disadvantages? 4. Can you measure all kinds of microbes this way? Why not?
