A new approach to the maintenance of large microbial populations for bioremediation purposes has beendeveloped in which a centrifugal bioreactor is used to immobilize microbial populations at extremely highdensity. The cells are ordered into a three‐dimensional array through which wastewater or groundwatervolumes 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 bioremediationneeds. The utilization of this new process has been explored for three different types of remediation: theremoval of heavy metals from wastewater, the aerobic degradation ofmethyl‐ tert ‐butyl ether (MTBE), and the anaerobic reduction of nitrateto nitrogen gas. This article discusses the use of centrifugal bioreactors and their application in remediation.© 2001 John Wiley & Sons, Inc.
