Metabolism of phenol and resorcinol in Trichosporon cutaneum

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...

Trichosporon cutaneum C.A.P.D. peritonitis.

Influence of various phenolic compounds on phenol hydroxylase activity of a Trichosporon cutaneum strain.

The phenol-degrading strain Trichosporon cutaneum R57 utilizes various aromatic and aliphatic compounds as a sole carbon and energy source. The intracellular activities of phenol hydroxylase [EC 1.14.13.7] of a Trichosporon cutaneum R57 strain grown on phenol (0.5 g/l) were measured. Different toxic phenol derivatives (cresols, nitrophenols and hydroxyphenols) were used as substrates in the rea...

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. ...
