Part 2: Problems PROBLEM 1 (15 points) For partial credit: (each time) correct set up; incorrect math: -1pt -1pt incorrect units (each time) incorrect set up: -4 for each y Pseudomonas sp. has a mass doubling time of 2.4 h when grown on acetate as completely the sole carbon source (assume this is the minimum doubling time corresponding -2 for each wirong to cells growing at ). The saturation constant for acetate is 1.3 g/l (a value which is unusually high) and the yield is Y = 0.46 g cells/g acetate. For a chemostat operated on a feed stream containing 38 g/l acetate calculate the following: y partially wrong x/acetate a) Critical dilution rate b) Cell concentration when the dilution rate is one-half the maximum. c) Substrate concentration at that condition. 64100nds
