title: [Phosphorus metabolism in yeasts, oxidizing hydrocarbons during active aeration of the medium].
abstract: Variations in the phosphorus and nitrogen assimilation by hydrocarbon oxidizing yeast C. guilliermondii K-5 were followed upon an active aeration of the medium  Changes in the phosphate forms of the acid-soluble and acid-insoluble fractions were found.  By the end of the lag-phase the content of all phosphate forms, except stable polyphosphates, increased.  At the onset of the active budding the content of labile phosphates, belonging to acid-soluble phosphates, increased.  As the culture developed, the content of these forms decreased and increased slightly in the growth phase with a negative acceleration.  Acid-insoluble polyphosphates were accumulated in the culture as long as it grew.  In the growth phase with a negative acceleration these polyphosphates were hydrolyzed.  This was responsible for an increment of all phosphates in the acid-soluble fraction.  The same pattern occurred in the dying phase of the culture.
