Technical Document

Brief Overview:

L-Tryptophan is an essential amino acid which important for growth and stress reducer. It also helps developing animal organs and optimalizing immune system. L-Tryptophan is commonly sythesized in the plants and microorganisms.

Manufacturing Process

L-tryptophan is produced by incubating a microbe capable of producing L-tryptophan and capable of constitutive expression of maleate synthase·isocitrate lyase·isocitrate dehydrogenase kinase/phosphatase operon in a culture medium so as to generate and accumulate L-tryptophan in the culture medium and harvesting the L-tryptophan. In commercial industry, Tryptophan is produced by biological synthetic based on fermentation process of serine and indole using either wild-type or genetically modified from bacteria such as B. amyloliquefaciens, B. subtilis, C. glutamicum or E. coli.

Animal Feed Industry

The product is widely used as premixture raw material and feed additive with following benefits:
• Provides essential amino acids for animals
• Provides essential for monogastric animals
• Increases animal production, animal performance, and animal weight gain
• Results in high efficiency due to shorter production cycle
• Enhances feed intake, since tryptophan is a precursor of the neurotransmitter serotonin, which affects the appetite
• Improves the digestive capacity of young animal particularly in the post-weaning period, whichreduce the frequency and severity of poor gut health and bacterial proliferation.
