PROBLEM 1 9 The bacteria X-Il can be described by a single Monod equation with maximum specific growth rate of 0.8 h 1, half saturation constant of 4 g/dm3, and Yp/X = 0.2 g/g, Yx/s = 4.5 g/g, Yx/02 = 1.19 g/g. The process is carried out in a chemostat in which the feed rate is 1000 dm3/h containing 10 g/dm3 of substrate. Question 1.1 What fermenter size in liters is needed to achieve 90% conversion of substrate
