Cytochrome P-450-dependent catabolism of triethanolamine in Rhodotorula mucilaginosa.
The yeast Rhodotorula mucilaginosa was able to grow in media containing triethanolamine or diethanolamine as the sole nitrogen source. During growth in the presence of triethanolamine, extracts of yeast cells contained increased levels of cytochrome P-450 dependent monooxygenase which catalyzed the oxidative N-dealkylation of aminoalcohols. Formation of diethanolamine, ethanolamine and glyoxylate from triethanolamine was demonstrated, and the identity of the products was verified by thin layer chromatography. These observations suggested the following scheme of triethanolamine catabolism: triethanolamine----diethanolamine + glycolaldehyde, diethanolamine----ethanolamine + glycolaldehyde, ethanolamine----NH3 + glycolaldehyde----glycolate----glyoxylate----glycerate pathway.

[Yeasts utilizing the surface-active substance Laurox-9].
Yeasts capable of utilizing the non-ionogenic surfactant Laurox-9 were identified as Cryptococcus humicolus (Daszewska) Golubev and Rhodotorula mucilaginosa (Jöerg) Harrison. IR spectrometry used for the quantitative assay of Laurox-9 showed that R. mucilaginosa utilized it as a sole carbon source. The first step of Laurox-9 metabolism was its hydrolytic cleavage yielding lauric acid and polyethyleneglycol. Optimal conditions were found for the electron-cytochemical localization of hydrolase involved in the primary degradation of Laurox-9 by yeasts. Its localization of the exocellular components was established.
