L-Tryptophan is an esential amino acid which important to amino acid balance in animal body and animal growth. It is important to creating neoratransmitter to produce serotonin to transmits signals between nerve cells and reducing stress. It also needed to develop organs and optimalized immun system in animal body. Process L-Tryptophan is commonly sythesized in the plants and microorganisms  Shikimic acid or Anthranilate.

Anthranilate will be condensed with phosphoribosylpyrophosphate (PRPP) and obtained pyrophosphate as a by-product. When the ring of the part of ribose is opened and subjected to reductive decarboxylation, It will resulted indole-3-glycerol phosphate, then transformed into indole.


Final process is,Indole and the amino acid serin will be calayzed and change their formation into Tryptophan. In commercial inndustry, Tryptophan is produced by biosynthetic based on

the  fermentation  of serine and indole using either wild-type or  genetically modified bacteria  such as  B. amyloliquefaciens , B. subtilis, C. glutamicum or E. coli. These strains was choosen due to carry mutations which prevent the reuptake of aromatic amino acids. Benefit


  1. Increasing animal production, animal prefomance, and animal weight gain
  2. High efficiency due to shorter production cycle
  3. High profit margin since reducing cost for feed production
  4. High degestible of L-Tryptophan
  5. It enhances feed intake, since tryptophan is a precursor of the neurotransmitter serotonin, which
  6. affects the appetite
  7. improves the digestive capacity of young animal particularly in the post-weaning period, which
  8. reduces the frequency and severity of poor gut health and bacterial proliferation.
