UTILIZATION OF AROMATIC-COMPOUNDS BY TRICHOSPORON-CUTANEUM KUY-6A

Trichosporon cutaneum KUY-6A, a cyclohexanecarboxylic acid-utilizing yeast, grew well on phenol, benzoic acid, the isomers of hydroxybenzoic acid (HBA), dihydroxybenzene and dihydroxybenzoic acid except 2.6-dihydroxybenzoic acid, but could not utilize aromatic compounds having Cl-, CH3- or NO2-groups or the isomers of phthalic acid. From the degradation behavior of all HBA isomers, it is concluded that strain KUY-6A can utilize all HBA isomers at concentrations higher than those reported previously. Furthermore, the culture conditions for o-HBA were found to differ considerably from those of m- or p-HBA. © 1990.
