what is k and r for each condition? K (carrying capacity): can be estimated by finding the point where the growth curve levels off. Take the average of this data point and all data collected beyond this point to estimate k (note: if the bacteria population is still growing, you can just take the last value of data for k. r: choose any two points at the log phase of growth. Then use the r formula. Just choose two waste conditions for r and k calculation so I can get the idea of how to do this, thanks.

what is k and r for each condition? 

K (carrying capacity): can be estimated by finding the point where the growth curve levels off. Take the average of this data point and all data collected beyond this point to estimate k (note: if the bacteria population is still growing, you can just take the last value of data for k. 

r: choose any two points at the log phase of growth. Then use the r formula. 

Just choose two waste conditions for r and k calculation so I can get the idea of how to do this, thanks.
