Zum Tryptophanabbau bei Cordyceps militaris-Stämmen in saprophytischen Kulturen

Summary The degradation of tryptophan in two strains of the Cordyceps miliraris Link in saprophytic culture was examined: both fungi showed different behavior patterns. In the strain I all the tryptophan is subject to lateral catenoid oxidation and the metabolite of this catabolism process are fixed. In strain II under identical experimental conditions the tryptophan is decomposed by the “Ehrlich-mechanism”. Independently of the above, N-acetylization reactions occur in both strains. Here both the L-isomers and the D-isomers of tryptophan are metabolized. Both isomers can be acetylized.
