At time zero a microbial population has a cell density of 100 cells/ml. After 12 hr the cell density is 140 cells/ml; after 24 hr it's 200 cells/ml; after 36 hr it's 280 cells/ml; after 48 hr it's 400 cells/ml. 1. Using the semi-log graph provided plot a growth kinetics curve using the data above. 2. What phase of growth is this microbial population in?_ 3. What is the generation (doubling time) of this microbial population?_ 4. Assuming the growth rate of these microbes is constant, what will the cell density of this population be after 72 hr?. After just 60 hr?
