FIG 7.

Nitrite consumption of the enrichment culture of AM1 at 16°C. Incubations were performed with transferred cells in early stationary phase and in mineral medium supplemented with various NH₄Cl concentrations (A) or NaCl concentrations (B). The experiments were started with inocula of 1% (A) and 10% (B). Noticeable results were obtained; thus, these experiments were performed once.
