Dynamics of denitrification activity of Paracoccus denitrificans in continuous culture during aerobic-anaerobic changes.
TL;DR: Induction and repression of denitrification activity were studied in a continuous culture of Paracoccus denitrificans during changes from aerobic to anaerobic growth conditions and vice versa, suggesting different modes of regulation for the three genes.

Analysis of bioavailable arsenic in rice with whole cell living bioreporter bacteria.
TL;DR: In this article, a multiwell plate bioassay was developed using genetically modified bacteria (bioreporter cells) to detect inorganic arsenic extracted from rice, which indicated that a major proportion of arsenic in rice is in the inorganic form.

TL;DR: The influence of repeated alternating aerobic-anaerobic growth conditions on the development of stable denitrification activity was studied with continuous cultures of Paracoccus denitrificans and with activated sludge to indicate that information on the induction process of denitrified activity in P. denitRificans can be used reasonably well to assess induction of denItrifying activity in more complex systems.

Inhibition of denitrification activity but not of mRNA induction in Paracoccus denitrificans by nitrite at a suboptimal pH
TL;DR: The influence of pH on the denitrification activity of a continuous culture of Paracoccus denitrificans was studied in relation to the presence of nitrite to indicate that either translation was somehow inhibited, or once synthesized nitrite reductase was inactivated, the enzyme could not be detected at sufficient amounts in the culture.
