흐름주입분석 기술을 이용한 젖산의 온라인 모니터링
Abstract
On-line monitoring technique for the concentration of lactate by a FIA(Flow Injection Analysis) system was studied. The lactate oxidase(LOD) was immboilized on VA-Epoxy carrier and integrated into the FIA system. The pH, buffer flow rate and temperature for the LOD-FIA were optimized, and the effects of salts and metabolites dissolved in the sample on the activity of immobilized enzyme were investigated. The LOD-FIA has been applied to monitor the concentrations of lactate in a simulated bioprocess. The on-line monitoring data by the LOD-FIA agreed with the off-line data measured by a fluorescence spectroscopy well.
