Question 1: If we start with a bacterial culture of 103 cells per mL and if the doubling time td is 1.5 h, calculate the final cell concentration (cells/mL) after 16 h.
Question 2: If 58 g of biomass was formed from one mole of glucose substrate, calculate the cell yield Y of the microbial culture.
Question 3: In a bioreactor the specific growth rate μ of a nitrifying bacteria population is 0.02 /h. What is the minimum mean cell residence time required?
Question 4: Assuming an exponential growth of a bacterial population with an initial number of cells X0 = 500 cells/L and a specific growth rate μ = 0.5 h-1, determine: (a) The cell concentration after 6 h; (b) The doubling time t0
Question 5: Write the Monod’s equation and show its graph. How would you go about computing the μmax and Ks?
