摘要：

Biofilm-immobilised cells of a Citrobacter sp. accumulated uranyl ion when challenged in a flow-through bioreactor. Uranyl ion deposition and activity of the mediating phosphatase were adversely affected by pre-storage of the biofilm at 4-degrees-C for 5-6 months. Pre-exposure to uranyl ion statically enabled recovery from the deleterious effect of storage and promoted subsequent bioreactor performance.
