title: [Growth inhibition by phenylalanine and tyrosine--metabolism of phenylalanine in Flavobacterium devorans (author's transl)].
abstract: Growth of a chloramphenicol-resistant mutant of Flavobacterium devorans (F. devorans r) was inhibited by L-phenylalanine and L-tyrosine and furthermore by L-tryptophan, 4-amino-benzoate, anthranilate and homogentisate. The inhibitionwas reversed partially by simultaneous addition of aromatic amino acids and 4-amino-benzoate. After cultivating F. devorans r in a glucose-minimal medium containing L-phenylalanine, the metabolites L-tyrosine, 4-hydroxyphenylpyruvate, 4-hydroxyphenylacetate, 4-hydroxybenzaldehyd, 4-hydroxybenzoate, homogentisate and anthranilate were found. Growth inhibition and a hypothetical degrading pathway of phenylalanine are discussed.
