In this project, a hollow fiber membrane reactor immobilized with Zymomonas mobilis ZM4 is proposed to overcome the inhibitory effects from toxic compounds. Actively growing Z. mobilis ZM4 immobilized within the porous matrix of asymmetric-wall hollow fiber membrane is protected by the membrane barrier between the toxic and the cells. Toxic compounds are added in varying concentrations and subsequent inhibitions on growth and ethanol production of the system are evaluated. The advantage of this system is that it could remove the pre-fermentation treatment, potentially reducing investment and operating cost.
