Biooxidation of 2-phenylethanol to phenylacetic acid by whole-cell Gluconobacter oxydans biocatalyst immobilized in polyelectrolyte complex capsules

Original language description

A high-performance biocatalyst in the form of encapsulated cells of Gluconobacter oxydans have been developed for production of phenylacetic acid (PAA) as a natural flavor component. Polyelectrolyte complex (PEC) capsules consisting of sodium alginate, cellulose sulfate, poly(methylene-co-guanidine), CaCl2, and NaCl were used for highly controlled and mild encapsulation of cells. Utilization of encapsulated G. oxydans cells was a significant improvement on existing data on operational stability of cellsand cumulative product concentration during biocatalytic production of PAA from 2-phenylethanol. Concerning operational stability, encapsulated cells were active over 12 cycles with a high biotransformation rate, while free cells were inactive after 7 cycles of use. The biocatalytic properties of encapsulated G. oxydans were tested in a bubble column reactor over 7 days with a final cumulative product concentration of 25 g/L. High cell viability (90%) was observed within PEC capsules by
