Figures
- FIG. 1.
Molecular structures of the cyclic nitramine explosives RDX, HMX, and CL-20.
- FIG. 2.
CL-20 biodegradation in microcosms. Soils from Florida (A), Iowa (B), and Texas (C) were incubated with CL-20. CL-20 amounts are in nanomoles per microcosm. ▪, active soil; ▴, soil with inhibited microbial activity. Degradation experiments were performed in triplicate. d, days.
- FIG. 3.
CL-20 biodegradation in enrichments with Florida soil. ▪, active soil; ▴, soil with inhibited microbial activity. Minimal medium was supplemented with succinate (20 mM) and CL-20 (100 μM). Enrichments were performed in triplicate. d, days.
- FIG. 4.
Growth of Agrobacterium strain JS71. Aerobic cultures were grown in medium with 20 mM succinate-0.1% (vol/vol) Tween 80 with (▪) and without (□) 250 μM CL-20 as the sole nitrogen source. ▴, CL-20 concentration. The growth studies were performed in triplicate (▪) or duplicate (□). d, days.
- FIG. 5.
Growth yield of Agrobacterium strain JS71 with 20 mM succinate and different concentrations of CL-20 (▪) or NaNO2 (▴). The CL-20 cultures were supplemented with 0.1% (vol/vol) Tween 80. All growth studies were performed in duplicate.
