FIG. 2.

Growth of Pseudomonas sp. strain FA1 at various concentrations of CL-20 (○) and (NH₄)₂SO₄ (•). The viable-cell count in early-stationary-phase culture (16 h) was determined for each nitrogen concentration. The linear-regression curve for (NH₄)₂SO₄ has a gradient of 0.122 and an r² of 0.990. The linear-regression curve for CL-20 has a gradient of 0.224 and an r² of 0.992. Data are means of results from duplicate experiments, and error bars indicate standard errors. Some error bars are not visible due to their small size.
