- Nicotiana tabacum cells are cultured to produce a polysaccharide gum. The reactor used is a stirred-tank reactor with an initial volume of 100 L. The maximum specific rate of growth of the culture is 0.18 d-1 and the yield coefficient of substrate in biomass is 0.5 gX/gS. The concentration of the limiting substrate in the medium is 3% (m/v). The reactor is inoculated with 1.5 g/L of cells and operated in batch until the substrate is exhausted, when the medium is fed with a constant flow rate of 8 L/d. The fed batch occurs in a quasi-steady state condition.a) Estimate the time of the batch step and the concentration of cells reached in this phase, considering exponential cell growth.b) The fed batch phase is carried out for a period of 40 days.

- Aspergillus can be used to produce α-amylase (α-AM), which is an enzyme that hydrolyzes the glycosidic bonds in starch molecules into maltose (disaccharide). Pure α-AM has a specific activity of 56.00 U/mg. The α-AM is secreted into the culture media during production (after 5 days, production is complete). Following, the Aspergilluscells are separated by centrifugation and discarded. The culture supernatant (with α-AM) is filtered giving a clarified supernatant with a volume of 100.0 L, activity of 3.00 U/mL, and total protein concentration of 0.650 mg/mL. After purification, the product stream (7.50 L) contains α-AM (25.00 U/mL) and a total of 6.788 x 103 mg total protein. Calculate the following: Concentration of total protein (g/L) and total units of activity in the clarified supernatant and purification product stream. Specific activities (U/g) of the clarified supernatant and purification product stream.
