Azotobacter chroococcum 34, actively growing on alpha-ketoglutaric acid, and Azotobacter chroococcum B and KL, which almost do not assimilate this acid, can grow on the majority of substrates of the tricarboxylic acid cycle and on glucose, with and without nitrogen. The rate of assimilation of alpha-ketoglutaric acid is several times higher in the cells cultivated in the presence of this acid than in the cells grown on other substrates. This difference seems to involve the mechanism of transport of alpha-ketoglutaric acid into the cell.
