Abstract L-Tryptophan (L-Trp) is an essential amino acid. It is widely used in medical, health
and food products, so a low-cost supply is needed. There are 4 methods for L-Trp …

Background: L-tryptophan is used widespread in the pharmaceutical industry. The majority
of L-Trp production depends on microbial processes that produce L-tryptophan from indole …

Tryptophanase, an enzyme with extreme absolute stereospecificity for optically active
stereoisomers, catalyzes the synthesis of l-tryptophan from l-serine and indole through a β …

Encapsulation is a well‐established process that allows formulation of a wide range of active
