Delivery of benzene to Alcaligenes xylosoxidans by solid polymers in a two-phase partitioning bioreactor.
Toxic levels of benzene were decreased to sub-inhibitory levels in a bioreactor via absorption by polymer beads or cylinders (poly(ethylene-co-vinyl acetate) or poly(styrene-co-butadiene)). After inoculation with Alcaligenes xylosoxidans, the remaining benzene in the aqueous phase as well as the benzene taken up by the polymers was degraded to completion. The capacity of these polymers for benzene, and benzene diffusivity within the polymers were also determined.
