Question

The maximum solubility of the alkane in the medium is 5 ppm. If the actual dissolved concentration of the alkane in the medium is 1 ppm. what conclusion may be drawn?

a.

The growth rate is limited by the rate of mass transfer of the alkane into the fermentation medium

b.

The growth rate is limited by the intrinsic kinetic properties of the cells and not by mass transfer

c.

The growth rate is neither mass transfer nor kinetically limited

d.

No conclusion on the growth rate can be withdrawn

Answer: (d).No conclusion on the growth rate can be withdrawn
