Elevated production of the aromatic fragrance molecule 2‐phenylethanol using Metschnikowia pulcherrima through both de novo and ex novo conversion in batch and continuous modes

摘要

BACKGROUND2‐phenylethanol (2PE) is a fragrance molecule predominantly used in perfumes and the food industry. It can be made from petrochemicals inexpensively, however, this is unsuitable for most food applications. Currently, the main method of production for the bio‐derived compound is to extract the trace amounts found in rose petals, which is extremely costly. Potentially fermentation could provide an inexpensive, naturally sourced, alternative.
