Abstract

A cell based biosensor for phenolic substances has been developed. The set up is based on a flow injection system with an expanded bed column with immobilised Pseudomonas cells. The cells were immobilised on glass particles pretreated with poly (ethylene diamine). The system responds to a range of phenolic substances. Storage and operational stabilities are good. The expanded bed concept makes the system reliable also when treating samples with particulate matter.
