Consider Example 16.1, where we demonstrated that two bacteria competing for a single nu-
trient in a chemostat (well-mixed) could not coexist. Consider the situation where B can ad-
here to a surface but A cannot. Redo the balance equations, where is the surface area
available per unit reactor volume and the rate of attachment is first order in with a rate
constant The sites available for attachment will be The attached cells can
detach with a first-order dependence on the attached cell concentration with a rate con-
stant of Attached cells grow with the same kinetics as suspended cells.
a. Without mathematical proofs, do you think coexistence may be possible? Why or
why not?
b. Consider the specific case below and solve the appropriate balance equations for
