Gene expression profiles of Nitrosomonas europaea, an obligate chemolitotroph [PDF]

open access: yes, 2005
Nitrosomonas europaea is an aerobic lithoautotrophic bacterium that uses ammonia (NH3) as its energy source. As a nitrifier, it is an important participant in the nitrogen cycle, which can also influence the carbon cycle.

Exploring the Nucleotide Specificity of Sucrose Synthase from Nitrosomonas europaea

open access: yes, 2020
In plants, sucrose is a major photosynthetic product, and it also plays an integral role in sugar sensing, development, and regulation of gene expression. Sucrose synthase, an enzyme found in plants, algae, and bacteria, catalyzes the cleavage of sucrose

Abundance and diversity of bacterial nitrifiers and denitrifiers and their functional genes in tannery wastewater treatment plants revealed by high-throughput sequencing.

open access: yesPLoS ONE, 2014
Biological nitrification/denitrification is frequently used to remove nitrogen from tannery wastewater containing high concentrations of ammonia. However, information is limited about the bacterial nitrifiers and denitrifiers and their functional genes ...
