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 (which is unusually high), 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 Cell concentration when the dilution rate is one-half of the maximum?
