[Formation and distribution of free amino acids in Cunninghamella elegans mycelium during growth on media with glucose and dodecane].
The growth, assimilation of organic nitrogen compounds, and production and distribution of free amino acids were studied during the growth of Cunninghamella elegans (--) 1204 on the defined medium 12 containing glucose and dodecane and without an additional carbon source (control). The culture utilized all leucine, glycine, and asparagine after three days of the growth, irrespective of the source of carbon in the medium. Glutamic acid was assimilated only in the presence of glucose. Some 15 free amino acids and 2 amides were detected in the cells, and also some correlations in the composition of the pool in the presence of different sources of carbon in the medium. The substitution of dodecane for glucose decelerates metabolism of free intracellular amino acids and stimulates their accumulation in the cells, especially if there is a deficiency of carbon sources: the overall content of amino acids and amides on the medium with glucose is from 2.2 to 4.1 mg/g; with dodecane, from 9.8 to 16.5 mg/g; in the control, from 16.4 to 25.8 mg/g.
