     continuous-flow chemostats were operated at different mean-cell-residence-times (θc) and influent concentrations of a xenobiotic (2,4-d) and biogenic substrates. steady state chemostat biomasses’ performances in 2,4-d degradation were analyzed with a mathematical model to determine the quantities of degrader the biomasses contained. the qualification for microbial cells to become degraders is a high grade of degradation kinetics. this qualification uniformly applies to all biomasses. the quantities of degraders vary inversely with the chemostats’ θc. biogenic substrates increase degrader yield such that a high biogenic and a high xenobiotic influent optimize degrader mass output. economics evaluation performed around the optima finds the influent containing 5–25% 2,4-d carbon (toc) in approximately 900 mg/l biogenic toc, and the θc of 2–5 d, are suitable operating conditions for a degrader producing bioreactor that may serve as a selector of biomass for bioaugmentation purposes.
