✦ Synopsis

Membrane-type reactors were prepared usmg a commercially available support In three test systems, mvolvmg glucose oxldase, glutammase and lactase, they compared favourably with packed-bed reactors m a flow-mJectlon set-up Although slmdar responses were observed for all reactor types, the membranes are easier to handle than mlcropartlcles When makmg contmuous m-hne measurements of bloprocesses at high samphng frequencies, the hfetlmes of packed beds of controlled pore glass were determmed by pressure budd-up wlthm the reactor When replaced wrth membrane reactors, no cloggmg was observed, the hfetlmes bemg determmed by loss of enzyme actlvlty Keywords Flow system, Enzyme reactor, Membrane reactor
