The rate of growth of Cunninghamella elegans (--) 1204 is higher on a mineral medium with glucose (6.56 g/litre) than on a mineral medium containing undecane, tridecane, and pentadecane (0.72--0.87 g/litre); all glutamic acid is consumed only from the medium with glucose. The cells contain 15--16 free amino acids and 1--2 amides, glutamic and aspartic acids and alanine prevailing. The culture grown on the medium with glucose contains asparagine, and the cells cultivated on the medium with alkanes contain histidine. Non-proteinogenous aminobutyric acids were found in the pool of the cells grown on all tested media with an exception of the medium containing undecane.
