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...

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. ...

The present study aimed to 1) determine the colonization rates of medically important Trichosporon species on normal perigenital skin and 2) determine the isolation rates of Trichosporon spp. isolated from the urine and catheters of Brazilian patients hospitalized in the Intensive Care Unit (ICU). The overall colonization rate of Trichosporon spp. was 11.15% (112 isolates). The most common spec...
