Characterization of microbial communities removing nitrogen oxides from flue gas: the BioDeNOx process.

BioDeNOx is an integrated physicochemical and biological process for the removal of nitrogen oxides (NOx) from flue gases. In this process, the flue gas is purged through a scrubber containing a solution of Fe(II)EDTA2-, which binds the NOx to form an Fe(II)EDTA.NO2- complex. Subsequently, this complex is reduced in the bioreactor to dinitrogen by microbial denitrification. Fe(II)EDTA2-, which ...

Microbial nitrogen transformations in earthworm burrows

Earthworms play an active role in soil nitrogen cycling. Past research has shown that earthworm castings are enriched in NO3 ÿ and NH4 + and show a high potential for microbial nitri®cation and denitri®cation. Little information is available on microbial populations and N transformations in the 1±2 mm thick soil lining of earthworm burrows (the drilosphere). We measured nitrifying bacterial pop...

Specific transformations of mineral forms of nitrogen in acid soils

Investigations were performed on soils of different acidity, ranging in the pH interval 4.65–5.80 (in water). Changes of the mineral nitrogen forms in the examined soils were studied by applying short-term incubation experiments performed under aerobic conditions, with a humidity of 30 % and a temperature of 20 °C, both with and without the addition of 100 and 300 ppm NH4–N. The results of the ...

Estimation of Microbial Biomass Carbon and Nitrogen in Bangladesh Soils

In order to estimate the microbial biomass content and to quantify the amount of available plant nutrients derived from microbial biornass in Bangladesh soils, biomass-C, -N, and available-N eoptents using samples from 8 soils were measured by applying the chloroform fumigation and drying-rewetting methods, respectively. 1)

Nitrogen Removing Biofilters for Onsite Wastewater Treatment on Long Island: Current and Future Prospects

Recent research has demonstrated that the approximately 360,000 septic tank/leaching systems and cesspools that serve 74% of homes across Suffolk County have caused the concentrations of nitrogen in groundwater to rise by 50% since 1985. This nitrogen-enriched groundwater is flowing into sensitive coastal environments where it has contributed to toxic algal blooms, oxygen-deprived waters, the l...
