It was found that a new compound of phenylalanine metabolites (2-hydroxy-3-phenyl-propenoic acid) and phenylacetic acid were formed in the cultured Czapek medium containing phenylalanine by Aspergillus sojae. 2-Hydroxy-3-phenylpropenoic acid (HPPA) was formed from phenylalanine (D-and L-form) via phenyllactic acid (D-and L-form), and degraded to benzoic acid, p-hydroxybenzoic acid, protocatechuic acid, and catechol in this order.
On the other hand, phenylacetic acid was formed from phenylpyruvic acid, and converted to homogentisic acid via o-hydroxyphenylacetic acid. From these results, a metabolic pathway of phenylalanine in Asp. sojae was proposed.
