Some enzymes, such as the one derived from fungi and investigated in this study, are able to produce valuable substances such as the fragrance (R)-1-phenylethanol. To this end, they convert a less expensive substrate using a co-substrate. A research team came up with the idea of supplying them with this co-substrate using a plasma — a somewhat crazy idea, as plasmas generally have a destructive effect on biomolecules. However, by employing several tricks, the researchers did indeed succeed. They have now refined one of these tricks and thus improved the process: They attach the enzymes to tiny beads in order to hold them in place at the bottom of the reactor, where they are protected from the damaging effects of the plasma.
