[Cultivation of feed yeasts on media with carbohydrates].

The different culture of yeasts oxidizing hydrocarbons and the accompanying microflora are, under certain physico-chemical conditions, in metabiotic relationships which provide stability of the system. These relationships were studied with yeast cultures belonging to the Candida genus and oxidizing hydrocarbons. The relationships between the hydrocarbon oxidizing yeast Candida guilliermondii and other species of the genus Candida were determined by a combination of active and passive antogonism, as the result of which strains of this species completely dominated in the cenosis of fermenters.
