C$.$ The specific oxygen demands and critical oxygen concentrations for typical microbial

and plant cell cultures are listed below:

Estimate kla required to achieve the cell concentrations, while maintaining the

dissolved oxygen concentration above critical

$($total is $3$ points$)$

Which cell culture has more oxygen transfer demand? Justify your answer. $1$

point

Given: The oxygen solubility in the media used for both cultures is $7\frac{g}{m^3}.$ Assume

steady state; no accumulation of oxygen at any location in the fermenter.
