(Submitter supplied) Nitrosomonas europaea is a chemolithoautotrophic bacterium that oxidizes ammonia (NH3) to obtain energy for growth on carbon dioxide (CO2), and can also produce nitrous oxide (N2O), a greenhouse gas. We interrogated the growth, physiological, and transcriptome responses of N. europaea to replete (> 5.2 mM) and limited inorganic carbon (IC) provided by either 1.0 mM or 0.2 mM sodium carbonate (Na2CO3) supplemented with atmospheric CO2. more...

(Submitter supplied) We analyzed the global transcriptional response of N. europaea when exposed to chloroform (7 µM for 1 h). Chloroform led to down regulation of 501 genes and up regulation of 251 genes. These up regulated genes included genes for heat shock proteins, sigmafactors of extracytoplasmic function subfamily and newly identified genes of toxin-antitoxin loci in N. europaea. Our study showed that despite a significant decrease of transcription in response to the stress, N. more...
