Atypical polyphosphate accumulation by the denitrifying bacterium Paracoccus denitrificans
Article Abstract:
It may not be necessary to recycle sludge between anaerobic and aerobic zones when using Paracoccus denitrificans as the polyphosphate-accumulating organism. This bacterium is capable of removing phosphate and nitrate without the need for alternating anaerobic/aerobic switches.`

Relationship between nitrite reduction and active phosphate uptake in the phosphate-accumulating denitrifier Pseudomonas sp. strain JR 12
Article Abstract:
Researchers describe a mechanism underlying the observed inverse relationship between phosphate uptake and nitrite reduction in Pseudomonas sp. strain JR 12. A c-type cytochrome appears to act as an intermediate in transferring an electron to both nitrite reductase and the site of active phosphate transport.

Light-mediated nitrite accumulation during denitrification by Pseudomonas sp. strain JR12
Article Abstract:
Photoinhibition of nitrite reduction caused light-mediated nitrite accumulation of Pseudomonas sp. strain JR12. This was gleaned in an examination of the effect of light on the denitrifying capacity of this nonphotosynthetic denitrifier. Inhibition of nitrite reduction in cells illuminated with green light was the highest, as against inhibition upon exposure to blue and red light. Exposure of the cells to light caused a photooxidation of cytochrome c, affirming that light exposure prevents electron flow from cytochrome c to nitrite reductase.
