1.	What do you mean by “Quasi steady state”?(a) Cell concentration remains virtually constant(b) Cell concentration is virtually variable(c) Total biomass remains constant with time(d) Total biomass decreases with timeI have been asked this question in class test.My doubt stems from Fed Batch Culture in portion Microbial Growth Kinetics of Bioprocess Engineering
Answer» CORRECT answer is (a) Cell concentration remains virtually CONSTANT Explanation: The total biomass in the CULTURE (X) increases with time, cell concentration (x) remains virtually constant, that is dx/dt ≅ 0 and therefore μ ≅ D. This situation is TERMED as a quasi steady state.
