Pseudomonas sp. has a mass doubling time of 2.4 h when grown on acetate. the saturation constant using this substrate is 1.3 g/l, and cell yield on acetate is 0.46 g cell/g acetate. if we operate a chemostat on a feed stream containing 38 g/l acetate, find the following (assume monod kinetics):

find the following:

a. maximum dilution rate

b. cell concentration when the dilution rate is one-half of the maximum

c. substrate concentration when the dilution rate is 0.8 dmax

d. cell productivity at 0.8 dmax
