Figures
- FIG. 1.
Structures of RDX, HMX, NDAB, MEDINA, and allantoin.
- FIG. 2.
Growth of Methylobacterium sp. strain JS178 in M-succinate and NDAB (1,300 nmol) as a sole N source. Shown are amounts of NDAB (▵), N2O (□), and NO2− (×). Growth is expressed as A600 (○). Error bars, standard deviations from duplicate experiments.
- FIG. 3.
Growth yield of Methylobacterium sp. strain JS178 in M-succinate, with nitrite (▵), ammonium (□), and NDAB (○) as N sources. The linear regressions have the following gradients: 0.00165 (R = 0.995) for nitrite, 0.00158 (R = 0.999) for ammonium, and 0.00173 (R = 0.999) for NDAB. Error bars, standard deviations from triplicate experiments.
- FIG. 4.
Incubation of [14C]RDX with Rhodococcus sp. strain DN22 (medium was supplemented with 10 mM succinate at day 25) (○), with Methylobacterium sp. strain JS178 (×), with both strains DN22 and JS178 (JS178 was reinoculated to the microcosms at day 42) (▵), and with the sequential addition of strain DN22 (used to transform [14C]RDX to [14C]NDAB) and NDAB-grown JS178 (added when 30% of [14C]CO2 was liberated from [14C]RDX, after the removal of DN22 cells by filtration) (□). Values are averages and standard deviations of duplicate experiments.
