1,5-diaminopentane, also known as cadaverine, is an important platform chemical having many applications in chemical industry. Bio-based production of 1,5-diaminopentane from renewable feedstock is a promising and sustainable alternative to the petroleum-based chemical synthesis.Here, we report development of a metabolically engineered strain of Escherichia coli that overproduces 1,5-diaminopentane in glucose mineral salts medium. The final engineered strain was able to produce 9.61 g /L of 1,5-diaminopentane with a productivity of 0.32 g/ L/ h by fed-batch cultivation. The strategy reported here should be useful for the bio-based production of 1,5-diaminopentane from renewable resources.[This work was supported by the Korean Systems Biology Research Project (20110002149) of the Ministry of Education, Science and Technology (MEST) through the National Research Foundation of Korea.
