A new approach to the maintenance of large microbial populations for bioremediation purposes has been developed in which a centrifugal bioreactor is used to immobilize microbial populations at extremely high density. The cells are ordered into a three-dimensional array through which wastewater or groundwater volumes may be flowed, unimpeded by frits or screens. The process methodology is independent of the type, shape, or viability of the individual cells immobilized and, thus, may be adapted to many different bioremediation needs. The utilization of this new process has been explored for three different types of remediation: the removal of heavy metals from wastewater, the aerobic degradation of methyl-tert-butyl ether (MTBE), and the anaerobic reduction of nitrate to nitrogen gas. This article discusses the use of centrifugal bioreactors and their application in remediation.
