Two uptake systems for phenol are identified in Trichosporon cutaneum. One is an inducible, high-affinity system, sensitive to protonophores. It is induced coordinately with phenol hydroxylase but can operate independently of phenol metabolism. The other is a constitutive, low-affinity system with different specificity and different pH optimum. It is not sensitive to protonophores.
