Which of the following techniques is best suited for immobilizing an affinity ligand?
During cultivation of microorganisms in a fermenter, various parameters are controlled by appropriate sensor (probe). Match each probe in Group I with the appropriate response mechanism in Group II.
The kinetics of the disintegration of baker's yeast cells in a bead mill is described as $$\frac{{dp}}{{dt}} = K\left( {{P_m} - P} \right)$$ , where P is the concentration of protein released, m is the maximum protein concentration achievable, K is the first order rate constant and is 0.5 h−1 for the system studied. The time required for the release of 90% of the intracellular proteins will be:
A mixture contains three similarly sized peptides P, Q and R. The peptide P is positively charged, Q is weakly negative, and R is strongly negative. If this mixture is passed through an ion-exchange chromatography column containing an anionic resin, their order of elution will be
In a chemostat, evaluate the dilution rate at the cell washout condition by applying Monod's model with the given set of data: \[{\mu _{\max }} = 1\,{h^{ - 1}};{Y_{\frac{X}{S}}} = 0.5\,g\,{g^{ - 1}};{K_S} = 0.2\,g\,{L^{ - 1}};{S_0} = 10\,g\,{L^{ - 1}}\]
Lysine is being produced in a lab-scale reactor by a threonine auxotroph. After 2 weeks of operation it was observed that the concentration of lysine in the reactor was gradually decreasing. Microbiological assays of reactor samples showed absence of contamination and recorded data showed no change in the operating conditions. The most probable reason for decrease in lysine concentration may be attributed to
In a fed-batch culture, 200 g L-1 glucose solution is added at a flow rate of 50 L h-1. The initial culture volume (at quasi steady state) and the initial cell concentration are 600 L and 20 g L-1, respectively. The yield coefficient \[\left( {{Y_{\frac{X}{S}}}} \right)\] is 0.5 g cell mass-g substrate-1. The cell concentration (g L-1) at quasi steady state at t = 8 h is
