| Taxonomy/phylogeny:
|
More than 50 species have been described within the genus Trichosporon and the following are assumed to be able to cause trichosporonosis: T. asahii, T. asteroides, T. cutaneum, T. dermatis, T. dohaense, T. inkin, T. loubieri, T. mucoides, and T. ovoides. Many of these species were earlier named T. beigelii, which is now an obsolete name. |
|---|
| Practical use: | T. cutaneum can be used for lipid production from biomass containing lignin and cellulose. Can also be used to degrade phenol and adsorb cadmium. |
|---|
| Comment: | Sometimes you see T. cutaneum mentioned among dermatophytes, but it is not normally considered as such. |
