title: Continuous steady-state method using tenax for delivering tetrachloroethene to chloro-respiring bacteria.
abstract: Tenax-TA, a solid-phase sorbent, was used as an alternative to hexadecane for continuous delivery of tetrachloroethene (PCE) to Desulfuromonas strain BB1, a chloro-respiring microorganism. In both batch and bioreactor configurations, Tenax not only maintained low, steady-state concentrations of PCE in an active culture for several months but also adsorbed the product of dechlorination, cis-1,2-dichloroethene, before it approached toxic levels.
