Lactobacillus casei is propagated under essentially
anaerobic conditions to provide a starter culture for manufacture of Swiss cheese.
The culture produces lactic acid as a by-product of energy metabolism. The
system has the following characteristics:
A stirred fermenter is operated in fed-batch mode at
quasisteady state with a feed flow rate of 4 m3 h-1 and
feed substrate concentration of 80 kg m-3. After 6 h, the liquid
volume is 40 m3. What mass of cells is produced after 6 h fed-batch
operation?
