Progress in biosythesis of diaminopentane / 生物工程学报

ABSTRACT

Air pollution and global warming are increasingly deteriorating. Large amounts of polyamides derived from fossil fuel sources are consumed around the world. Cadaverine is an important building monomer block of bio-based polyamides, thus biotechnological processes for these polymers possess enormous ecological and economical potential. Currently, the engineered strains for biological production of cadaverine are Corynebacterium glutamicum and Escherichia coli. We review here the latest research progress of biosynthesis of cadaverine including metabolism of cadaverine in microorganisms, key enzymes and transport proteins in cadaverine synthesis pathway, optimum pathways and cadaverine yields.
