A concentrated solution of the limiting substrate is added in fed-batch at a rate?
(a) Greater than the solution of the limiting substrate and the same medium used to establish the batch culture
(b) Less than the solution of the limiting substrate and the same medium used to establish the batch culture
(c) Equal to the solution of the limiting substrate and to the same medium used to establish the batch culture
(d) Negligible to the solution of the limiting substrate and to the same medium used to establish the batch culture
I have been asked this question in examination.
Query is from Fed Batch Culture topic in chapter Microbial Growth Kinetics of Bioprocess Engineering
