[Dependence of the activity of L-amino acid oxidase in the fungus Aspergillus niger R-3 on the source of nitrogen in growth media]. / Aktivnost' oksidazy L-aminokislot u griba Aspergillus niger R-3 v zavisimosti ot istochnoka azota v srede.

Various populations of peroxisomes in cells of Aspergillus niger R-3 were formed under the growth in media containing 0.5% glucose and various sources of nitrogen (1/4 of optimal concentrations of (NH4)2SO4, L-alanine, and L-methionine). Different levels of of L-amino acid oxidase activity were found in these populations of peroxisomes.
