Aromatic compounds make up a large part of fragrances and are traditionally produced by chemical synthesis and direct extraction from plants. Chemical synthesis depends on petroleum resources and has disadvantages such as causing environment pollutions and harsh reaction conditions. Due to the low content of aromatic compounds in plants and the low yield of direct extraction, plant extractions require large amounts of plant resources that occupy arable land. In recent years, with the development of metabolic engineering and synthetic biology, microbial synthesis of aromatic compounds from renewable resources has become a promising alternative approach to traditional methods. This review describes the research progress on the synthesis of aromatic fragrances by model microorganisms such as Escherichia coli or yeast, including the synthesis of vanillin through shikimic acid pathway and the synthesis of raspberry ketone through polyketide pathway. Moreover, this review highlights the elucidation of native biosynthesis pathways, the construction of synthetic pathways and metabolic regulation for the production of aromatic fragrances by microbial fermentation.
