A mixed culture of Candida tropicalis and Trichosporon cutaneum was carried out using a n-paraffin medium. The growth of C. tropicalis was markedly enhanced by the mixed culture with T. cutaneum which did not grow on n-paraffin. C. tropicalis extracellularly excreted free fatty acids as metabolic products of n-paraffin in the culture medium. T. cutaneum appeared to assimilate these free fatty acids which were growth inhibitors for C. tropicalis, threreby enhancing the growth of C. tropicalis.
