- A culture consisting of 100 litres of nutrient medium containing 12 g l-1 of growth limiting substrate is inoculated with 10g of bacteria in a batch fermenter. The yield of biomass from substrate is 0.05 g g-1 . The maintenance coefficient is 2.0 g g-1 h -1 . The specific rate of product formation due to maintenance is 1.0 h-1 . The maximum specific growth rate of the organism is 0.3 h -1 . YPX= 7.7 and product formation is directly linked with metabolism. a) What is the time required to produce 15 g of biomass? !!!!! ANS IS 3.07 HRS!!!! STEPS on how to reach this pleaseIs the Mueller-Hinton Agar (MHA) a complex or defined medium? Explain based on its composition. Is MHA a A) differential, B) selective, C) both differential and selective media, or D) neither? Explain based on what kind of microorganisms it allows to grow.Why must the poured Mueller-Hinton Agar not be too shallow?
- What is the description of the growth and growth pattern of the microorganisms streaked on Coconut Water Agar or Nutrient Broth?Type of Growth: Surface or Sub-surface?What is the growth pattern in the three streaked areas?Why does counting multiple fields of view and calculating the average increase confidence in thw accuracy of the result? Why do we use a log phase culture of tetrahymena instead of a stationary phase culture? What effect do you think growth phase may been feeding rate?How would a facultative anaerobe growth curve change if it was placed in the presence of oxygen environment? If the organism were to be placed in an anaerobic environment during log phase, how would the growth curve look?
