  1. PTT 203Biochemical Engineering Kinetics MICROBIAL GROWTH IN continuous CULTURE WEEK 11-12 By: MADAM NOORULNAJWA DIYANA YAACOB

  2. Lecture Outline • Introduction • Continuous Growth Characteristics • Dilution Rate, Optimum Operation

  3. Cell growth in Continuous Culture

  4. Cell growth • The net specific growth rate is the difference between a gross specific growth rate (μg, h-1) and the rate of loss of cell mass due to cell death (kd, h-1): • Microbial growth can also be described in terms of cell number, N: where μR is the net specific replication rate (h-1)
