[Nitrogen fixation in combined cultures of Lipomyces and bacteria]

Nitrogen fixation by pure cultures of soil yeasts belonging to the genus Lipomyces Lodder et Kreger van Rij was not found by the acetylene method on a medium containing microelements and yeast autolysate. In a binary culture of L. lipofer 133 and Pseudomonas sp. 5, a nitrogen fixing bacterium, the content of bound nitrogen was 3.6 times higher in aerobic conditions and 15 times higher in anaerobic conditions than its accumulation by individual bacterial culture.
