Research Abstract

In this study, a novel screening method for enzyme-displaying yeasts were investigated. Enzyme-displayed yeast cells were captured in the micro-sized calcium alginate beads each by each using newly developed reverse micelle method to prevent diffusion of hydrolyzed fluorescent substrates. Adopting flow sorting to these captured cells, active cells were successfully enriched. This system would be a useful method for high speed screening of yeast cells which display various hydrolyzing enzymes with high activity.
