Instructions to the candidates :
1) Attempt a total of five questions selecting atleast two questions from each
section.
2) Answers to the two sections must be written in separate books. 3) Neat diagrams must be drawn wherever necessary. 4) Figures to the right indicate full marks.
SECTION - I
Q1) a) Discuss mass transfer by molecular diffusion in a fermenter. [8]
b) Discuss the kinetics of product formation by microbial culture in terms
of growth linked products in batch and fed batch cultures. [8]
Q2) Explain why biotransformation is widely seen as Green alternative over
conventional chemical routes. Outline the difference between cell and enzyme based biotransformation.
What is measure of volumetric oxygen transfer rate in a fermenter? How
KLa is derived in a fermenter.
[16]

[16]
Q6) Outline downstream processing steps for the recovery of recombinant vaccine
and Penicillin. [16]
Q7) Discuss genetic and metabolic pathway engineering as mean for microbial
strain improvement. [16]
Q8) Describe design of a fermenter suitable for cultivation of mammalian cells and
why? Explain immobilized cell reactors and hollow fiber bioreactors. [16]
