Alpha-Terpineol production from an engineered Saccharomyces cerevisiae cell factory
Abstract Background Alpha-Terpineol (α-Terpineol), a C10 monoterpenoid alcohol, is widely used in the cosmetic and pharmaceutical industries. Construction Saccharomyces cerevisiae cell factories for producing monoterpenes offers a promising means to substitute chemical synthesis or phytoextraction....
