where l is specific growth rate, S is the oleic acid concentration
in culture broth, SF is the oleic acid concentration
in feeding medium (891 g l1
), and S0 is the
initial oleic acid concentration in culture broth (2 g l1
).
The constant feeding rate for a definite period of time
was calculated so that the same amount of oleic acid
could be supplied by constant feeding as that would be
exponentially fed during the time interval.
