CM 4710, Biochemical Processes Fall 2007 Homework #4 Fri. 05 Oct., '07 1. Batch Growth of Lactobacillus on Glucose.

The following data were measured for the growth of Lactobacillus on glucose, starting with

different initial substrate (Glucose (S)) at constant initial cell concentrations (Xo).

Plot each data set (A, B, and C) in an appropriate manner to determine whether any lag phase

is present. From the appropriate data set, determine µmax. Determine the value of KS.

Calculate the Yield over the entire batch time period for each data set. 2. Growth Parameters of E. aerogenes in a Chemostat.
