A recombinant micro-organism producing resveratrol by a pathway in which phenylalanine ammonia lyase (PAL) produces trans-cinnamic acid from phenylalanine, cinnamate 4-hydroxylase (C4H) produces 4-coumaric acid from said trans-cinnamic acid, 4-coumarate-CoA ligase (4CL) produces 4-coumaroyl CoA from said 4-coumaric acid, and resveratrol synthase (VST) produces said resveratrol from said 4-coumaroyl CoA, or in which L-phenylalanine- or tyrosine-ammonia lyase (PAL/TAL) produces 4-coumaric acid, 4-coumarate-CoA ligase (4CL) produces 4-coumaroyl CoA from said 4-coumaric acid, and resveratrol synthase (VST) produces said resveratrol from said 4-coumaroyl CoA. The micro-organism may be a yeast, fungus or bacterium including Saccharomyces cerevisiae, E. coli, Lactococcus lactis, Aspergillus niger, or Aspergillus oryzae.

The disclosure provides an engineering bacterium for ferulic acid production, a preparation method of the bacterium and use thereof. The invention provides an engineering bacterium that can efficiently produce ferulic compounds by expressing a series of heterologous enzymes in a host cell through gene recombination technology. The expression system constructed by the invention has low metabolic background, strong heterologous expression ability and low cost. The system can synthesize the end product through relatively simple steps, and provide a new way for the industrial production of ferulic acid, intermediates or derivatives thereof.

The present invention relates to a recombinant microorganism which is modified to be capable of producing diosmin and hesperidin and to the use thereof for producing diosmin and/or hesperidin.

A cell may include heterologous polynucleotides encoding a multienzyme complex involved in the metabolic pathway of phenylpropanoids and biosynthesis of a vanilloid or a hydroxybenzaldehyde precursor thereof, which multienzyme complex comprises enzymes for the biosynthesis of coumaric acid and a crotonase.
