abstract = {Corynebacterium glutamicum is an important organism in
industrial biotechnology for the microbial production of
bulk chemicals, in particular amino acids. However, until
now activity of a complex catabolic network for the
degradation of aromatic compounds averted application of C.
glutamicum as production host for aromatic compounds of
pharmaceutical or biotechnological interest. In the course
of the construction of a suitable C. glutamicum platform
strain for plant polyphenol production, four gene clusters
comprising 21 genes involved in the catabolism of aromatic
compounds were deleted. Expression of plant-derived and
codon-optimized genes coding for a chalcone synthase (CHS)
and a chalcone isomerase (CHI) in this strain background
enabled formation of 35 mg/L naringenin and 37 mg/L
eriodictyol from the supplemented phenylpropanoids
p-coumaric acid and caffeic acid, respectively. Furthermore,
expression of genes coding for a 4-coumarate: CoA-ligase
(4CL) and a stilbene synthase (STS) led to the production of
the stilbenes pinosylvin, resveratrol and piceatannol
starting from supplemented phenylpropanoids cinnamic acid,
p-coumaric acid and caffeic acid, respectively. Stilbene
concentrations of up to 158 mg/L could be achieved.
Additional engineering of the amino acid metabolism for an
optimal connection to the synthetic plant polyphenol
pathways enabled resveratrol production directly from
glucose. The construction of these C. glutamicum platform
strains for the synthesis of plant polyphenols opens the
door towards the microbial production of high-value aromatic
compounds from cheap carbon sources with this
microorganism.},
