Phenethyl alcohol (2-phenylethanol, 2-Phenylethyl alcohol, Benzeneethanol, Phenylethanol) is an antimicrobial, antiseptic, and disinfectant that is used also as an aromatic essence and preservative in pharmaceutics and perfumery.
Phenethyl alcohol has been shown to interact with the cytoplasmic membrane of other microorganisms in various ways. Escherichia coli phenethyl alcohol, at a concentration higher than that used to induce myxospore formation, inhibits growth by causing a breakdown in the cellular permeabihty barrier. At lower concentrations, phospholipid synthesis, uptake of gentian violet in E. coli and the uptake of several amino acids by Neurospora crassa were all inhibited by phenethyl alcohol[1].

Biosynthesis of floral scent 2-Phenylethanol in rose flowers
Biosci Biotechnol Biochem 2016 Oct;80(10):1865-73.PMID:27297332DOI:10.1080/09168451.2016.1191333.
Plants emit chemically diverse volatile compounds for attracting pollinators or putting up a chemical defense against herbivores. 2-Phenylethanol (2PE) is one of the abundantly emitted scent compounds in rose flowers. Feeding experiments with l-[(2)H8]phenylalanine into rose flowers and subsequent analysis using gas chromatography-mass spectrometry analysis revealed the hypothetical biosynthetic intermediates to [(2)H8]-2PE, and the biochemical and genetic analyses elucidated the principal pathway to [(2)H8]-2PE. We recently found season-specific 2PE pathway producing [(2)H7]-2PE from l-[(2)H8]phenylalanine. This is a unique example where the dominant pathway to a specific compound changes with the seasons. This review focuses on the biosynthesis of floral volatiles and their regulation to adapt to the changes in the environment.
Bioprocesses for 2-Phenylethanol and 2-phenylethyl acetate production: current state and perspectives
Appl Microbiol Biotechnol 2018 Dec;102(23):9991-10004.PMID:30293195DOI:10.1007/s00253-018-9384-8.
2-Phenylethanol (2-PE) and 2-phenethyl acetate (2-PEA) are valuable generally recognized as safe flavoring agents widely used in industry. Perfumes, pharmaceuticals, polishes, and personal care products, are some of the final products using these compounds as additives due to their rose-like odor. Also, 2-PE is used in disinfectants, pest control, and cleaning products due to its biocide capability. Although most of these additives production are derived from chemical synthesis, the current trend of consumers to prefer natural products has contributed to the development of biotechnological approaches as an alternative way to obtain natural 2-PE and 2-PEA. The most efficient route to bioproduce these compounds is through the bioconversion of L-phenylalanine via the Ehrlich pathway, and most of the advances have been focused on the development of this process. This review compiles the most recent developments in the biotechnological production of 2-PE and 2-PEA, indicating the most studied strains producing 2-PE and 2-PEA, the current advances in the in situ product recovery in liquid systems, an overview of the strain developments, and the progress in the use of residue-based systems. Future research should address the need for more sustainable and economic systems such as those using wastes as raw materials, as well as the scale-up of the proposed technologies.
[Advances in biosynthesis of 2-Phenylethanol by yeasts]
Sheng Wu Gong Cheng Xue Bao 2016 Sep 25;32(9):1151-1163.PMID:29022316DOI:10.13345/j.cjb.150539.
2-Phenylethanol (2-PE) is an aromatic alcohol with a pleasant rose-like fragrance. It has been widely used in food, cosmetic, and pharmaceutical industry. Most of 2-PE is produced by chemical synthesis, but the use of chemically synthesized product is restricted in some fields. 2-PE from plant extraction is natural but its production is very low. Microbial biotransformation is a promising process to produce natural 2-PE. In this paper, we review recent research progress in the synthetic metabolic pathways and regulatory processes of 2-PE in yeast, and strategies for improving 2-PE production. Moreover, we discuss the limitation of current progress and future research directions.
Biotechnological production of 2-Phenylethanol
Appl Microbiol Biotechnol 2002 Jun;59(1):1-8.PMID:12073125DOI:10.1007/s00253-002-0992-x.
2-Phenylethanol (2-PE) is an important flavour and fragrance compound with a rose-like odour. Most of the world's annual production of several thousand tons is synthesised by chemical means but, due to increasing demand for natural flavours, alternative production methods are being sought. Harnessing the Ehrlich pathway of yeasts by bioconversion of L-phenylalanine to 2-PE could be an option, but in situ product removal is necessary due to product inhibition. This review describes the microbial production of 2-PE, and also summarizes the chemical syntheses and the market situation.
Current status and perspectives of 2-Phenylethanol production through biological processes
Crit Rev Biotechnol 2019 Mar;39(2):235-248.PMID:30570367DOI:10.1080/07388551.2018.1530634.
2-Phenylethanol (2-PE), an important flavor and fragrance compound with a rose-like smell has been widely used in the cosmetics, perfume, and food industries. Traditional production of 2-PE was mainly through the extraction from plant materials or by chemical synthesis. However, the increasing demand of consumers for natural flavors cannot be met by these methods. Biological production of 2-PE has emerged to be an appealing solution due to an environmental friendly process and the definition of a "natural" product. In this review, we have comprehensively summarized the current status and perspectives for biological 2-PE production in terms of its advantages over classical chemical synthesis and extraction from natural plants. A comprehensive description of 2-PE synthetic pathways and global regulation mechanisms, strategies to increase 2-PE production, and the utilization of agro-industrial wastes as feedstocks has been systematically discussed. Furthermore, the application of in situ product removal techniques have also been highlighted.
