Effect of nitrate and nitrite to the chemotactic responses of CC-124 vegetative cells in different media. Vegetative cells in TAP-N ($■$); TAP-N supplied with nitrate (5 mM) ($■$), and TAP-N supplemented with nitrite (5 mM) ($■$) were assayed for chemotaxis to 5 mM nitrite or 5 mM nitrate as indicated. Data are means ± SD of 3 independent experiments.
