Formation of 2,6-dihydroxyphenylacetic acid from phenylacetic acid by Trichosporon cutaneum.

Degradation of 4-hydroxyphenylacetic acid by Trichosporon cutaneum.

Trichosporon cutaneum degraded 4-hydroxyphenylacetic acid to acetoacetic and malic acids. 3.4-Dihydroxyphenylacetic acid, an intermediate in the reaction sequence, underwent hydroxylation before the benzene ring was cleaved.

Uptake of phenol by Trichosporon cutaneum.

The soil yeast Trichosporon cutaneum, which is distinguished by having a strictly oxidative metabolism, can be induced to utilize phenol as a sole carbon source. The present paper shows that such phenol-induced cells contain a specific, energy-dependent uptake system for phenol. Phenol uptake is not directly linked to its o-hydroxylation inside the cell, the first step of phenol metabolism. The...

cis,cis-Muconate cyclase from Trichosporon cutaneum.

The inducible enzyme catalysing the conversion of cis,cis-muconate to (+)-muconolactone was purified 300-fold from the yeast Trichosporon cutaneum, grown on phenol. The enzyme has a sharp pH optimum at pH 6.6. It reacts also with several monohalogen derivatives and with one monomethyl derivative of cis,cis-muconate, but not with cis,trans- or trans,trans-muconate or 3-carboxy-cis,cis-muconate. ...

Production of phenylacetic acid by anaerobes.

We tested 388 strains of anaerobes from 17 genera for the production of phenylacetic acid. The compound was found in only two genera (Bacteroides and Clostridium) but not within all the species of these genera.
