WebYou have decided to design a CSTR with recycle to degrade TCE (trichloroethylene) cometabolically by aerobic phenol-utilizing bacteria. To do this, you will feed phenol (C 6 H 5 OH; as a C source) and oxygen, along with required nutrients, to the reactor in order to grow a population of bacteria that can fortuitously degrade TCE. The problem is to first … northern 2021WebThe present invention relates to a single CSTR bioreactor equipped with a cell recycle unit, and a multi-stage CSTR bioreactor system in which 2-7 such single CSTR bioreactors are connected in series with each other.
