1 Environmental and Pollution Microbiology Exam 3 Review, LYoung material 1. Growth µ = µ m S - b K s + S What is µ ? What is µ m ? What is S ? What is Ks ? Can the Monod growth curve for 2 different organisms have different µ m but the same Ks? Can you draw them? Can the Monod growth curve for 2 different organisms have the same µ m but different Ks? Can you draw them? Can organism 1 have a higher µ m and a lower Ks than organism 2 which would have a lower µ m and a higher Ks. Can you draw them? Under each of the above conditions, can you identify which organism would out compete the other under high S conc (higher than Ks) and which would grow better at low S conc (lower than Ks)? 2. Understand what is Y (yield). Why is Y so different for aerobes vs anaerobes (such as in wastewater treatment)? 3. What is generation time, doubling time? 4. In batch growth system, what is happening to cell conc? what is happening to substrate conc? 5. In a batch growth curve, how would you determine doubling time? 6. In a batch growth curve, what is limiting cell growth in the stationary phase? 7.
