Nitrates 37-44 radixin Homo sapiens 32-35 12153019-9 2002 The presence of nitrate reversibly halted RDX metabolism, whereas ammonium had no discernible effect, which implies that: (i) nitrate, which commonly occurs in RDX-contaminated groundwater, may inhibit in situ RDX metabolism, and (ii) although RDX may act as both a nitrogen source and cometabolic electron sink, the latter role predominates, as RDX reduction will proceed regardless of whether or not a more favorable nitrogen source is present.

Nitrates 88-95 radixin Homo sapiens 21-24 35065174-0 2022 Enhanced bioremediation of RDX and Co-Contaminants perchlorate and nitrate using an anaerobic dehalogenating consortium in a fractured rock aquifer. Nitrates 67-74 radixin Homo sapiens 27-30 35065174-2 2022 Bioremediation of RDX is feasible through biostimulation of native microbes with an organic carbon donor but may be less efficient, or not occur at all, in the presence of the common co-contaminants perchlorate and nitrate. Nitrates 215-222 radixin Homo sapiens 18-21 35065174-7 2022 In microcosms with groundwater containing perchlorate and nitrate, RDX degradation began without delay when bioaugmented with 10% WBC-2. Nitrates 58-65 radixin Homo sapiens 67-70 16345884-6 1981 Anaerobic treatment of RDX wastewaters, which also contain high nitrate levels, would permit the denitrification to occur, with concurrent degradation of RDX ultimately to a mixture of hydrazines and methanol. Nitrates 64-71 radixin Homo sapiens 23-26 28442008-2 2017 The present study investigated the biotransformation of RDX and HMX by anaerobic granular sludge under sulfate- and nitrate-enriched conditions. Nitrates 116-123 radixin Homo sapiens 56-59 28442008-3 2017 The results showed that RDX and HMX could be transformed by anaerobic granular sludge when nitrate was present. Nitrates 91-98 radixin Homo sapiens 24-27 28442008-4 2017 However, the biotransformation of RDX and HMX was negatively influenced, especially with high nitrate concentrations. Nitrates 94-101 radixin Homo sapiens 34-37 28442008-6 2017 The removal of RDX and HMX under both nitrate- and sulfate-enriched conditions was facilitated by the use of glucose as additional substrate. Nitrates 38-45 radixin Homo sapiens 15-18 23215531-2 2013 The detection of vapors from the low volatility explosive compound RDX was achieved through selective atmospheric pressure chemical ionization using nitrate reactant ions (NO(3)(-)) and NO(3)(-) HNO(3) adducts generated in an electrical discharge source. Nitrates 149-156 radixin Homo sapiens 67-70 23215531-6 2013 Recorded signals were observed for RDX concentrations below 25 ppq using selected ion monitoring (SIM) of the RDX-nitrate adduct at m/z 284.

Nitrates 114-121 radixin Homo sapiens 110-113 21327803-11 2011 RDX biodegradation activity by the T7 isolate was inhibited in the presence of nitrate or ammonium concentrations above 1.6 and 5.5 mM, respectively (100 mg l(-1)) while the T9N isolate"s activity was retarded only by ammonium concentrations above 5.5 mM. Nitrates 79-86 radixin Homo sapiens 0-3 21327803-13 2011 RDX-degrading activity by the Rhodococcus species isolate T9N may have important implications for the bioremediation of nitrate-rich RDX-contaminated aquifers. Nitrates 120-127 radixin Homo sapiens 0-3 21327803-13 2011 RDX-degrading activity by the Rhodococcus species isolate T9N may have important implications for the bioremediation of nitrate-rich RDX-contaminated aquifers. Nitrates 120-127 radixin Homo sapiens 133-136 18499297-9 2008 Dissolved RDX samples were degraded in the laboratory and results showed that all reproduced degradation processes released nitrate with a strong fractionation. Nitrates 124-131 radixin Homo sapiens 10-13 18499297-10 2008 Laboratory isotopic values for RDX-derived NO(3)(-) produced a trend of high delta(18)O-low delta(15)N to low delta(18)O-high delta(15)N, and groundwater samples with nitrate concentrations above the expected background level appeared along this trend. Nitrates 167-174 radixin Homo sapiens 31-34 18499297-11 2008 Our results thus point toward a characteristic field of isotopic ratios for nitrate being derived from the degradation of RDX.
