Project Overview

The iGEM (International Genetically Engineered Machine) competition is the premier synthetic biology competition for undergraduate students worldwide. The XJTU-CHINA 2019 team designed and built a Bacterial Fragrance Generator — an engineered Escherichia coli system capable of biosynthesizing sleep-promoting aromatic compounds.

Sleep disorders affect a significant portion of the global population. Aromatherapy using natural compounds such as linalool (found in lavender) and limonene (found in citrus peels) has been shown to have calming and sleep-promoting effects. The project aimed to engineer E. coli to produce these terpene compounds via the MEP pathway, enabling an affordable, scalable biological alternative to chemical synthesis.
