A fluidized-bed, immobilized-cell bioreactor is used for the
conversion of glucose to ethanol by Z. mobilis cells immobilized in
k-carrageenan gel beads. The dimensions of the bed are 10 cm (diameter) by 200
cm. Since the reactor is fed from the bottom of the column and because of CO2
gas evolution, substrate and cell concentrations decrease with the height of
the column. The average cell concentration at the bottom of the column is X0
= 45 g/l, and the average cell concentration decreases with the column
height according to the following equation:
where Z is the column height (cm). The specific rate of
substrate consumption is qS = 2 g S/g cells. h. The feed flow rate
and glucose concentration in the feed are 5 l/h and 160 g glucose/l,
respectively.
Determine the substrate (glucose) concentration in the effluent

Frederick Griffith accidentally discovered transformation when attempting to develop a vaccine for pneumonia. He injected mice with samples from S-strain (virulent) and/or R-strain (nonvirulent) pneumococci bacteria (Streptococcus pneumoniae). Which of the following results is NOT consistent with Griffith's experiments?
